Here comes the report of a scary 2.2.12 crash.
I hope the information is sufficient, please send suggestions,
comments, complaints to me.

[7.] Environment
Was running KDE on a machine with 'only' 48M RAM ;)

[7.1.] Software (add the output of the ver_linux script here)
up-to-date SuSE 6.1 system with a tailormade 2.2.12 kernel

[7.2.] Processor information (from /proc/cpuinfo):
[7.3.] Module information (from /proc/modules):
[7.4.] SCSI information (from /proc/scsi/scsi)
I do not have the above information right here, since it is a friends
machine, but I can get them if needed.
