oops in 2.4.0test12-pre5+reiserfs+crypto

[Florian Schmitt]

I had the following oops while doing a "find -name" and playing mp3s on 
my SB live:

It seems strange that the oops occured in ne2k-pci, since no network was 
connected at that time.

No it did not.  This is the broken klogd oops converter making a mess
of the report.  Always run with "klogd -x" and run ksymoops manually.

If you're running 2.4.0-test12-pre5 or later with reiserfs, you should be 
aware that this can be unsafe due to a problem with reiserfs_writepage.
Fortunately, Chris Mason just posted a patch to fix this on the reiserfs-list,
against reiserfs-3.6.22.  The recent reiserfs-list archives can be found at:

http://marc.theaimsgroup.com/?l=reiserfs&r=1&w=2&b=200012

This may have nothing to do with your oops, but if you're going to run
2.4.0-test12-pre5,6,7 then go get the writepage.diff patch, and apply it
after applying linux-2.4.0-test10-reiserfs-3.6.22-patch.

Of course, this is bleeding edge, so the usual caveats apply.

Good luck,
Steven
