Well your CC worked, mine evidently didn't. ;)

No, that was the whole trace. Sometimes it doesn't even give that much,
just the first 4 lines.

Not really - me IDE is only 65Mb and is full of the TOS stuff since my
SCSI drive got cleard for NetBSD. ;) At most I could move my swap
partition to the IDE drive (would it work from there?)

I'm tempted to suspect that too, since most times it happens there
is intense disk activity going on - e.g. compiling something, or
very annoyingly while fsck is fixing the filesystem after the last crash.
Using the 1.1 SCSI-driver sounds attractive to me since I never
had problems with that one. If it didn't take 16 hours (assuming no
crashes) to build my own kernels I'd experiment a lot more myself.

Great! :)
