Subject2.2.20pre10, Oops with ide/scsi
Hi,

I've a DVD and a burner, both are on the same ide channel. I use
ide-scsi
emulation.
I've installed an audio disk in the DVD reader and tried toi read it
with
'xcdroast'. The automounter was active. I got a oops (description
follows) and
this oops was followed by many many others and finally a complete crash
of the
machine, even the magic keys where not active.

here are the messages and the raw oops, then the oops prcessed by
ksymoops. This is the only oops I've found in the log, many others
followed this one ...
