[Dell XPS 15 (L502X)] Kernel panic during boot

[Swarnendu Biswas]

I am using Ubuntu Gnome 14.04 LTS. I am experiencing kernel panic and boot failure very frequently for the last couple of weeks.

Let me know what more information can I provide. It seems that the failure should be very easily reproducible.

Can you take a picture of the panic and attach it to the bug report?

[Joseph Salisbury (jsalisbury)]

May be similar to bug 1318322

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 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'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Thanks for the suggestions, I have installed and am testing kernel build 3.15-rc5.

[Swarnendu Biswas (swarna-cse)]

The issue has not reappeared since I have started testing 3.15-rc5.

[Swarnendu Biswas (swarna-cse)]

I will try. Unfortunately today I observed another kernel failure, but this was not while booting. I was using Skype when the kernel failure appeared.

[Swarnendu Biswas (swarna-cse)]

Any suggestions on whether I should use the -generic packages or the -lowlatency ones?

[Swarnendu Biswas (swarna-cse)]

Well there was a kernel panic with 3.15-rc5. I am not sure if the failures are related. I have added a snapshot of the failure. Please let me know if I can try out something else.

[Swarnendu Biswas (swarna-cse)]

I made made almost 5-6 attempts but can't even login to my system with kernel 3.15-rc7. I am facing this problem intermittently with versions 3.15-rc7, 3.15-rc5, 3.14.1, 3.13-27.

Not sure if this could be because of other missing packages or dependencies. Any ideas?

[penalvch (penalvch)]

Swarnendu Biswas, did this problem not occur in a release prior to Trusty?

[Swarnendu Biswas (swarna-cse)]

No I didn't experience this before the Trusty release.

However, I sometimes use alpha builds and upgrade/downgrade packages. During the process, I was once stuck on a old kernel which was not getting updated (3.13-16 I think). I installed the Ubuntu release kernel 3.13-24 manually.

The problems have started since then, so I am thinking whether the problem can be related to my package configurations.

Is there a way to sanity check my packages and configurations?

Yes, reinstall. Please advise if this would be still reproducible.
