[Bug 1429959] fix eeh on qla2xxx
------- Comment on attachment From thadeul@xxxxxxxxxx 2015-04-16 18:57 EDT-------
Mauricio and I have investigated this, and found out that there is a code that checks for all FF's and might set the HBA offline and release queues, which might even crash the system, during our tests.
The attached patch seems to fix all the problems we have seen, including
when the adapter seems to have recovered, but can't do any IO.
We have tested this on top of 4.0.
Mauricio, can you build a package with this patch on top of Vivid's
kernel, so this can be tested?
Thanks.
Cascardo.

Title:
Auto Error Recovery is failing after error injected for sailfish card
in Ubuntu 14.10 [PowerNV]
Status in linux package in Ubuntu:
New
Bug description:
---Problem Description---
PowerNV/Ubuntu 14.10 Auto Error Recovery is failing after error injected for sailfish
---uname output---
Linux powerio-le21 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:55:08 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux
Machine Type = 8286-42A
---Steps to Reproduce---
There are 2 LUNs coming across 3 different paths and multipath is configured.
1. Run I/O activity by running HTX load on the multipath devices.
2. Verify I/O activity on the multipath devices by iostat command
2. Injected error by the following command in
echo 0x8000000000000000 > /sys/kernel/debug/powerpc/PCI0001/err_injct_inboundA;
sleep 1;
echo 0x0 > /sys/kernel/debug/powerpc/PCI0001/err_injct_inboundA
3. The error injection happened and the I/O activity was suspended as confirmed by iostat.
4. Error recovery of the PCI devices did not happen and the devices remained inaccessible.
The dmesg during the event is as follows

Please find the host kernel log details in the attachment.
I don't see any suspecting points from EEH core side. It seems that
the device driver failed to resume the device as expected. Could you
please ask device driver developer to take a look on this? Maybe the
device driver missed some fixes. Also, it would be worthy to have a
test on linux upstream as well to see if that works or not.
Thanks,
Gavin
I performed the EEH test on Ubuntu 14.04.2 ( 3.16.0-29 Linux kernel)
I am facing the same issue there as well.
As of now, this has been tested on Ubuntu 14.04.1,14.04.2 and 14.10.
This issue appears in Ubuntu 14.04.2, Ubuntu 14.10 and 15.04
Rajesh, could you reload the driver with the parameter
ql2xextended_error_logging set to 0x00200000 and rerun the EEH test?
This should enable additional logs that might be useful in order to
debug this issue. Could you attach the full dmesg output of this test
to the bug?
Bear with me since this is the first time I work with this adapter / driver, but this particular section of the log sounds a bit worrying to me, I will take a look at the driver to see if I can figure out how it works:
[ 502.258629] qla2xxx 0001:07:00.1: Direct firmware load failed with error -2
[ 502.258630] qla2xxx 0001:07:00.1: Falling back to user helper
[ 502.259236] qla2xxx [0001:07:00.1]-0063:5: Failed to load firmware image (ql2500_fw.bin).
[ 502.259354] qla2xxx [0001:07:00.1]-0090:5: Fimware image unavailable.
I'll also take a look if we are missing any patches in the Ubuntu
release that might solve this issue.
Looking at the log it is mentioned that slot reset returned 5, looking
at pci.h it means that the value returned was
PCI_ERS_RESULT_RECOVERED, so the device driver is fully recovered and
operational.
I am taking a look at the drivers code as to why the driver is failing
to resume the adapter.
