[Bug 910941] Re: After installing bootchart on Precise, intermittent reboots result in a kernel panic

 

Patrick Wright, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

** Tags removed: kernel-request-3.2.0-10.17 kernel-request-3.2.0-14.23 kernel-request-3.2.0-8.14 kernel-request-3.2.0-8.15
** Tags added: needs-kernel-logs needs-upstream-testing

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  After installing bootchart on Precise, intermittent reboots result in
  a kernel panic

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Boot Speed Testing has been running consistently for a few weeks now.
  I've noticed with Precise images that the tests intermittently fail at
  the same step in the tests.

  After the system is initially installed and booted the bootchart
  package gets installed.  Once installed the OS is rebooted twice to
  account for the changes bootchart makes to ureadahead, kernel, etc.

  This issue that is randomly encountered after the first reboot results
  is a kernel panic.

  See attachment.
