Package: kernel-image-2.6.8-1-686
Version: 2.6.8-3
My gateway/fileserver machine running Debian Unstable was unresponsive
this morning. When I plugged in a monitor and keyboard, I saw:
possible deadlock in kmem_alloc (mode 0x50)
on the screen. I was unable to get the machine to reboot, so I hit the
reset button. After a reboot, I looked at /var/log/syslog and found
thousands of messages (see below). I'm not a kernel hacker by any
means, so I'm submitting this in hopes that someone else can make sense
of it and forward it upstream, if appropriate.
Just briefly, the machine is a Pentium III 1.0 Ghz, ASUS TUSI-M
motherboard, 384MB SDRAM. I have XFS on /dev/md0 mounted at /raid is a
RAID1 array over two parallel ATA drives (/dev/hde and /dev/hdg); Debian
is installed on an EXT3 partition on /dev/hda, also a parallel ATA
drive.
Here is the first message in syslog. I have the entire relevant portion
of syslog saved (size is ~690k), as well as the machine's dmesg, if
necessary. Please let me know if I can help in any other way.

Version: 2.6.8-99+rm
You reported a bug against the Linux kernel (version 2.6.8) that was
shipped with Debian 3.1 (sarge). Since Debian 3.1 is no longer
supported and the kernel has changed so much that it would be very
difficult to verify every outstanding bug from 2.6.8, I'm hereby
closing your bug report.
If you still see this issue with the kernel from the upcoming release
of Debian (lenny, version 5.0), then please me know and I'll be happy
to reopen this bug report.
Thanks.
