SubjectOops with 2.2.17pre19
Hi,
here's a crash report.

[1.] One line summary of the problem:

Linux-2.2.17pre19 has crashed (with Oops).

[2.] Full description of the problem/report:

Linux-2.2.17pre19 has crashed. The system wasn't connected to a
network, so I can't say, wether it still was reachable via a
network. Unfortunaly somebody unexperianced was working at the
machine and he didn't know about Magic SysRQ keys, so he just
rebooted.

[4.] Kernel version (from /proc/version):

Linux version 2.2.17pre19 (root@privat) (gcc version 2.95.2 20000220
(Debian GNU/Linux)) #2 Thu Aug 24 18:03:13 CEST 2000

[5.] Output of Oops.. message (if applicable) with symbolic
information
resolved (see Documentation/oops-tracing.txt)

End of assembler dump.

[7.] Environment

It's a Debian 2.2 system used as a dialup workstation. It's running
XFree86 (3.3.6) all the time. No special programs were running.

This should be all the modules, which were loaded during the crash,
except vfat and fat.

[7.5.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):

The hd's settings are adjusted with 'hdparm -X66 -m16 -c1 /dev/hda'.
/proc/ide/hda/model says: WDC AC26400B. 'hdparm' reports the
following:

/dev/hda:
multcount = 16 (on)
I/O support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 784/255/63, sectors = 12594960, start = 0

I'm not sure, but the soundcard _might_ have caused the
problem. (under win98 the system turned even more unstable after the
sound card was installed.) It's a 'Cirrus Logic CS 4614/22/24
[CrystalClear SoundFusion Audio Accelerator'.

The kernel configuration:
http://hp9001.fh-bielefeld.de/~moritz/config

Would any information would be helpful or is there something I could
do?
