kernel panic on bootup

[Paul Roeland]

version 3.13.0-61-generic generates a kernel panic right in the bootup on an Aspire E1-111 (Celeron N2930). It happens so soon that it doesn't register in the syslog.

Strangely enough, it did boot up one time in 'debug mode', the dmesg from that is included.

Most of the time it does the kernel panic there as well, though. Versions earlier than 3.13.0-61 work fine.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1480921

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Due to nature of the issue, I cannot run apport-collect. The best I can do is a (literal...) screenshot

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Also, can you capture and post a screen shot of the panic?

Screenshot is in comment #3.

I will test with upstream kernel later

[Paul Roeland (systeembeheer-e)]

Did tests, with following result:

- 4.2.0-rc5 upstream: works (although wifi driver missing but that's unrelated)
- 3.19.0-25-generic (from 'linux-generic-lts-vivid'): works
- 3.16.0-45-generic (from 'linux-generic-lts-utopic'): works

3.13.0-57 and earlier: works (tested: 57, 55, 54, and various lower ones)

3.13.0-58, 3.13.0-59, 3.13.0-61, kernel panic (see comment #3 for screenshot)

so it appears the regression was introduced in 3.13.0-58, and later kernel series have no issues.
