BUG: unable to handle kernel paging request at ffffc900051f5000

This change was made by a bot.

Do you have a way to reproduce this bug or was it a one-time event?

This has happened only once so far, after there was a kernel upgrade. I haven't faced it since.

this bug happens from time to time for me. can't directly reproduce it, it happens randomly.

I'm getting this all the time since the last couple of days, any logs I can attach to help when it happens? It seems to happen directly on login but everything seems to work as normal.

same with me. occours randomly at start up.

This change was made by a bot.

this didn't happen on login for me.

That bug is ranked 16 on this week e.u.c issues
https://errors.ubuntu.com/problem/88ad8fa1d4300f3e9a9506ceaba3b7b3396c9379

setting to high, it has 260 reports on the error tracker

Tengo el mismo error :-(

This looks like a similar issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1050964

I can reproduce this bug by opening Settings->Appearance and trying to close it. The Settings Dialog becomes unresponsive.

This happens when I start games, i.e. Counterstrike: Source or Left 4 Dead 2.
Using R9 280X with radeon driver on 14.04 beta2 everything updated.

Found this bug when switching user accounts.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 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.

Patch being discussed upstream:
http://lkml.iu.edu//hypermail/linux/kernel/1402.0/02540.html

crashed while playing music by rhythmbox

Setting-security freezing.

I can reproduce this. I first noticed it during a failed boot when I accidentally left an old USB boot drive in the USB port. Later I was running some Phoronix stress tests, which crash and show the same error in the crash report details being sent to [who?].

Anyway, it crashes on the following test:
124: TTSIOD 3D Renderer - Processor

First I noticed it when running the processor test suite. But then I could run this test alone and still recreate it. It happens about 60-90 seconds into the test. The test itself just hangs at that point.

The following commit is in 3.13 upstream as of 3.13.9:
fa82051 make prepend_name() work correctly when called with negative *buflen

Trusty has the 3.13.9 updates as of: 3.13.0-24.46

Can folks apply the latest Trusty updates and confirm if this bug still exists or not? If it does still exists, then commit fa82051 is not the fix and further investigation is needed.

Same thing for me :-((
