I am seeing this problem on OpenSUSE with kernel-desktop versions 3.15.6
(stable repo) and 3.16.0 (HEAD repo).

The log files on my laptop, /var/log/messages and /var/log/warn, will
grow HUGE with the following repeated over and over along with some
extraneous related log entries:

2014-08-15T12:18:41.396981-04:00 localhost kernel: [17310.691176] r592: IRQ: card added
2014-08-15T12:18:41.396983-04:00 localhost kernel: [17310.691178] r592: IRQ: DMA error
.
<snip>
.
2014-08-15T12:18:41.397001-04:00 localhost kernel: [17311.223846] r592: IRQ: card added
2014-08-15T12:18:41.397004-04:00 localhost kernel: [17311.223847] r592: IRQ: DMA error

On any given day, there will be tens of thousands of these entries such
that /var/log/messages and /var/log/warn will both exceed 3GB within a
day (over 6GB total).

I believe that this bug is generated due to the presence of a Ricoh
R5C592 Memory Stick Adapter on my laptop and which has never been
properly recognized by the stock linux kernels. Apparently, the kernel
developers keep trying to make it work but have now introduced a
"bigger" problem so to speak since it is now causing all these
extraneous error messages to be generated in the logs.

I am seeing this bug on OpenSUSE with kernel-desktop versions 3.15.6 and
3.16.0. This bug does not appear to be present in the OpenSUSE stock
3.11.6 and 3.11.10 kernels. I have since reverted back to the earlier
kernels that don't have this problem.

This bug has also been reported at Red Hat's bugzilla at:

https://bugzilla.redhat.com/show_bug.cgi?id=1119361

IMHO, this bug needs to be fixed prior to the release of OpenSUSE 13.2.

FYI,

Gordon

Reproducible: Always

Steps to Reproduce:
1. Boot
2. Wait a while. It sometimes takes an hour or two for the log errors to begin at top volume.
Actual Results:  
Logs grow *HUGE* with r592IRQ: DMA errors and related entries.

Expected Results:  
Logger should not produce error messages of this magnitude and size.

Yes, you should learn how to build a kernel and a patched module.  There are a few good ways.  I'll give some brief instructions later.

You're testing 3.15 and 3.16, so the above statement doesn't fit at all.

No, r592 developer has to submit the fix to the upstream at first.  This
is the golden rule.  In general, we take *only* the upstream fix (or the
patch that is promised to upstream) to openSUSE kernels.

If there is a problem of upstreaming, put me in Cc in chain, so that I
can assist for it.

A quick way to rebuild a module is like below:

1. Install kernel-source and kernel-desktop-devel packages.

2. Copy the relevant driver code to the local directory.  Suppose you'll work on a directory /somewhere/test to compile the module:
   % mkdir /somewhere/test
   % cp -a /usr/src/linux/drivers/memstick/host /somewhere/test

3. Patch the code.  In this case, pass -p4 to strip the paths:
   % cd /somewhere/test
   % patch -p4 < /yetsomewhere/r592.patch

4. Build the module.  This is the tricky part.  Pass -C option to make.
   % make -C /usr/src/linux-obj/x86_64/desktop M=$(pwd) modules

5. If successful built, install it to the updates directory.  Do this as root.
   % su
   ....
   # mkdir -p /lib/modules/$(uname -r)/updates
   # cp *.ko /lib/modules/$(uname -r)/updates
   # depmod -a

6. Confirm that the module will be loaded from the new path.  The command below should give the path with "updates" path:
   % /usr/sbin/modinfo r592 | grep filename
   filename: /lib/modules/..../updates/r592.ko

7. Retest.  If anything goes wrong, just remove the updated modules from
/lib/modules/*/updates/* directory.

Since this rebuilds only a few modules, it won't take time at all, at
most 5 minutes or so.

I have found a resolution to this problem as is described in the Red Hat
bug report here:

https://bugzilla.redhat.com/show_bug.cgi?id=1119361

That is, set the following parameter in the kernel config file
/boot/<kernel version>:

CONFIG_MMC_RICOH_MMC=n

On my recently upgraded OpenSUSE 13.2 machine, the kernel was
3.16.6-2-desktop so the file that I modified was
/boot/config-3.16.6-2-desktop.

The log messages will then subside completely.  Otherwise, if you have
the ricoh r592 card reader then your logs will grow exponentially.  For
example, after I upgraded to OpenSUSE 13.2 two days ago,
/var/log/journal had grown to over 5GB in less than 48 hours.

The problem is the default setting should be CONFIG_MMC_RICOH_MMC=n
instead of CONFIG_MMC_RICOH_MMC=y.  So, the kernel developers need to
change this parameter for all OpenSUSE versions.

Gordon

Thanks, that's a good information.

Though, CONFIG_MMC_RICOH_MMC was also y in the old working kernel, so
disabling this is no real solution unless confirmed to *all* Ricoh MMC
chips.

If the Kconfig matters, the bug must be in drivers/pci/quirks.c, and
indeed there were a few changes regarding Ricoh MMC device there between
3.15 and 3.16 kernels.

Could you give hwinfo output of your machine?  I particularly need the
PCI IDs, but it's better to have all hwinfo in anyway.

Sorry!  My PC was stable with minimal log entries for an hour or two
last night. Then, today it started generating huge logs again even with
CONFIG_MMC_RICOH_MMC=n.  So, as a test, I blacklisted r592 in
/etc/modprobe.d/50-blacklist.conf.  Its been 5 hours since then without
any excessive logging.  Interestingly, the SD card reader works properly
too even after I black listed r592. So, blacklisting  r592  (with
CONFIG_MMC_RICOH_MMC=n) has stopped the excessive logging and the SD
card still works.  I have attached the results of the lspci and hwinfo
commands.  As you can see, there are actually four RICOH devices listed.
I hope that this helps.

Also, I am running nVidia proprietary drivers which I would have to
recompile in order to try out the other more recent kernels so
installing these kernels (and reverting back to stock) will be a bit
more time consuming than otherwise.  Nevertheless, if you still want me
to test these newer kernels, I will do so within the next week or so.

Thanks very much for your assistance!

Well, your kernel-desktop version 3.16.7-1.g632515b-desktop did not
help.  Like before, after installing your new kernel, everything was
fine through a few hours or operation and 3 to 4 suspends/resumes.
Then, following the most recent resume from suspend, the massive logging
started back up again.   I have attached a 12 second snippet of the log
output that I hope helps you figure this out.

To review what is happening, everything is fine for a  few hours of
operation.  Then the kernel logger goes crazy with huge massive logging.
I believe that the massive logging has always begun following a resume
from suspend, however, I cannot say that with 100% certainty. Then,
following a reboot, everything is fine again for a little while.

Please review the attached log and reply with your advice.  This is an
unmanageable situation.  If it cannot be fixed soon then I need to
revert back to an earlier kernel version and, if necessary, an earlier
OS version such as OpenSUSE 13.1.

As another test, I am going to blacklist r852 since it has been showing
up in these logs too.

Thanks again for your help.

OK, then maybe it isn't a regression that was introduced in 3.16 but did

Just to confirm: does the card reader work even without r592 module at
all?  I saw you blacklisted, but it isn't loaded at all when using the
card reader?

Yes, the card reader works without the r592 module.  I have now
blacklisted both r592 and r852 and there are no mention of either in the
kernel logs at startup or when I plug the card in.  Also, the hwinfo
command indicates that both modules are not active even when the card is
inserted during which I am able to browse the card.

I am adding another hwinfo output file with r592 and r852 blacklisted.
This file was generated with the SD card inserted and working. The
hwinfo output says that both R592 and r852 are not active.  However,
there are two other Ricoh devices:

Device 32: PCI 301.0: 0c00 FireWire (IEEE 1394) (OHCI)
Model: Model: "Ricoh R5C832 IEEE 1394 Controller"
Driver: "firewire_ohci"

Device 33: PCI 301.1: 0805 SD Host controller
Model: "Ricoh R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter"
Driver: "sdhci-pci"

So, should I also blacklist both firewire_ohci and sdhci-pci?

Thanks,

Gordon

PS: As an FYI, I am now running OpenSUSE 13.2.  Previous to three days
ago, I was runing OpenSUSE 13.1.  I don't know if it matters but I
thought that I should mention this.

Yes, you can keep using the SD-card, etc, without r592 and r852 modules.
r592 module is only for the legacy memory stick device, and r852 is for
xD.  Unless you need these rare media, you can safely blacklist them.

Did you have to blacklist both modules, not only one of them?  I wonder
now whether disabling DMA in r592 and r852 modules make things calm
down.  Put the following in /etc/modprobe.d/*.conf:

  options r592 enable_dma=0
  options r852 r852_enable_dma=0

I am going to watch and wait before I disable DMA for the two modules. I

immediately disable DMA to see if that helps.

With this configuration, everything seems to be back to normal.  As an

I noticed that you posted an updated kernel on November 27 which I did
install.  Did that update contain anything special or significant
regarding this problem?

Also, do you recommend that I stay on your kernel/repo or should I
revert back to the stock kernel at some point?

Please advise.

  r592 IRQ: DMA errors cause log files to grow *HUGE*

Status in linux package in Ubuntu:

  Fix Released

Bug description:
  Hi,
  Since some recent time, my log files (syslog & kern.log) grow huge, making the computer unusable when it performs logrotate operations.
  Having a look to that, I see it contains many many lines :
  Sep 27 09:50:44 mmb-laptop kernel: [42839.496635] r592: IRQ: DMA error
  Sep 27 09:50:44 mmb-laptop kernel: [42839.599027] r592: IRQ: card added

  It seems related to this device : Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 12)
  I do not use it and I do not need it for now.

  I am using Ubuntu 15.04 with latest updates (as of 27-sep-2015),
  kernel 3.19.0-28-generic #30-Ubuntu on x86_64.

  I've read some posts/other bug reports related to the same issue :
