BUG: unable to handle kernel paging request at ffffb4ff // ext4_get_acl+0x80/0x210

[Martin-Éric Racine]

On my Ubuntu+1 test host, kernel 3.0 is extremely unstable. Exactly what happens is unknown to me, however, apparently, Apport caught some of the issue and suggested sending this report.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel currently in the release pocket than the one you tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help.

[Martin-Éric Racine (q-funk)]

Yes, it still applies.

[Martin-Éric Racine (q-funk)]

Please note that this issue prevents further action on bug #807564.

[Martin-Éric Racine (q-funk)]

Brad Figg, I already answered that it still applies and changed it to confirm. I'd appreciate if you took notice of that, in the future, instead of asking me twice to test the same thing.

[Martin-Éric Racine (q-funk)]

Brad,
Thanks for the heads up. Once 3.0.0-12.19 has propagated, I'll check whether or not it works any better than previous releases.

[Brad Figg (brad-figg)]

@ Martin-Éric Racine

The tag that you removed is used to know which versions you have been asked to test. Since you removed it, you were asked to test it again. The instructions in the comment said nothing about removing tags.

Brad

[Martin-Éric Racine (q-funk)]

As confirmed by Bug #858840 against linux-image-3.0.0-12-generic 3.0.0-12.19, this is still unresolved.

[Martin-Éric Racine (q-funk)]

Confirmed. See bug #870603.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[Martin-Éric Racine (q-funk)]

Downloaded and installed this one:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-rc9-oneiric/linux-image-3.1.0-0301rc9-generic_3.1.0-0301rc9.201110050905_i386.deb

Will re-enabled kernel-oops and report as soon as I can get a trace.

[Martin-Éric Racine (q-funk)]

It appears that this kernel lacks 'vesafb' so I'm unable to see if anything goes wrong or not.

Trying to instead use the native 'lxfb' also failed, even though it's compiled as a module, because that module is blacklisted in /etc/modprobe.d/blacklist-frambuffers.conf

[Martin-Éric Racine (q-funk)]

So far so good with 3.1.0-1.1 generic on Precise. :)

Hi all,

I just experience an error (twice) after trying to copy files from a network drive to a local hard disk (log, see below).

Should I report this as a duplicate or is this something else? Please your advice.
