[Bug 1237392] Re: kernels following version 3.8.0-27 do not start

 

I was able to determine those upstream versions by looking at the Saucy
changelog.  The Ubuntu 3.8.0-27 kernel was based off of upstream
3.8.13.4 and we know that did not have the bug.  The Ubuntu 3.8.0-28
kernel was based off of upstream  3.8.13.5, so it was just a matter of
testing and confirming.

The next step is to perform a kernel bisect to identify the exact commit
that introduced this regression.  It will require testing about 6
kernels, which I will build and post links to here.  After I build a
kernel, I'll post a link to it here for you to download and test.  After
your testing, I'll build the next kernel based on your results if the
test kernel had the bug or not.  Eventually it will narrow down to one
commit.

I'll post a link shortly with the first test kernel.

Title:
  kernels following version 3.8.0-27 do not start

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  All kernel updates on ubuntu following kernel 3.8.0-27 result in an
  empty screen with no indication of startup, no response to the
  keyboard. I can only start up using kernel version 3.8.0-27-generic.
  All following numbers (up to and including 3.8.0-31-generic) do not
  result in a running system. Also, the display no message at all when
  starting up (after grub).

  I checked the logfiles with "grep -n "Linux version 3.8.0-" *" and
  found only 27 to be logged, nothing for the other kernels. I am at a
  loss how to continue.

  I am running the most recent version of Ubuntu server.

  Two days ago I reinstalled Ubuntu with essentially the same result.
  The installation kernel version 3.8.0-19 works fine. The updated
  kernel 3.8.0-31 does not work.

  The following is the situation:

      When I let the machine start on itself I get no output at all.
      When I manually tell ubuntu to start the most recent kernel, I get 2 lines:

  "Loading Linux-3.8.0-31-generic ..." "Loading initial ramdisk ..."

  that's it.

      When I manually start the recovery kernel, I get a lot of
  information. Finally it drops to a terminal and indicates it could not
  load the LVM partition /dev/mapper/Server-Root. This is why I never
  see any result in my message or dmesg on disk.

  The problem seems to be with the Areca Raid controller. It does a
  reset of the scsi bus eh until it finally gives up and drops to a
  terminal. A while after the system goes berserk with messages of non
  responding scsi bus.

  As I cannot reach my harddisk, is there a way to find out what is
  wrong? Why does everything work fine up to and including kernel 27 and
  starts to malfunction after that? Did the Areca software change in
  some way?

  P.S. When I start kernel version 3.8.0-19, everything works fine.
