Description Sean E. Millichamp 2006-11-06 02:43:59 UTC

Description of problem:

When using NFS with the cachefilesd backend for cachefs (against a fully patched
CentOS 4.4 server), I got this:

The system the error occurred on is a dual-core Pentium M.  Shortly before the
kernel BUG I got an SMP related kernel opcode error.  Unfortunately, I don't
have a record of the exact error.

Version-Release number of selected component (if applicable):
# rpm -q kernel
kernel-2.6.18-1.2798.fc6

How reproducible:
This is the first one I've encountered.

Comment 1 Sean E. Millichamp 2006-11-06 12:59:18 UTC

Okay, it is reproducable :/.  I don't know how consistently, but 2 in less then
12 hours (most of which I spent sleeping) counts in my book:

Each time I had just finished some extended heavy NFS use (NFS mounted homedirs).

Comment 2 Sean E. Millichamp 2006-12-10 17:24:15 UTC

Still occurring with the latest kernel.  At the time of the crash I was editing
some files over my NFS mounted homedir in vim and playing Oggs in Rhythmbox over
NFS.

Comment 3 Jon Stanley 2007-12-31 21:54:26 UTC

Reassigning this to RHEL4 kernel instead of FC6.

Comment 4 Jeff Layton 2008-01-04 19:29:54 UTC

Not sure why this was moved to a RHEL4 kernel bug. All of the oopses seem to be
from FC6 kernels, and RHEL4 doesn't have any sort of cachefs. I'd be interested
to know if this is reproducible on a more recent kernel, but not sure whether
cachefs is in shape enough there to be usable...

Comment 5 Jon Stanley 2008-01-04 19:42:50 UTC

Oops, I just read the text of the bug and not the oopses - my bad.  The text
says CentOS 4.4.  That'll teach me not to believe everything I read next time! :)

However, FC6 has reached end-of-life.  Please re-try this on F7 or F8.

Comment 6 Jon Stanley 2008-01-08 01:54:44 UTC

(This is a mass-update to all current FC6 kernel bugs in NEW state)

Hello,

I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug, however this version of Fedora is no longer
maintained.

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

Comment 7 Jon Stanley 2008-02-08 04:27:50 UTC

Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA,
since no information has been lodged for over 30 days.

Please re-open this bug or file a new one if you can provide the requested data,
and thanks for filing the original report!
