Subjectproblems with scsi stuff in 2.1.130
FInally I tried to use the 2.1.130 kernel. With the iminent release of 2.2 I thought 2.1.130 should be stable enough. Unfortunately I ran into problems with some scsi stuff. While trying to record a cd, I got an oops:

Since it is my first oops, I have no idea what to do with it.

Another problem occurred when I tried to do "cdparanoia -d /dev/scd2 -g /dev/sg4 -Q" on a Mixed-Mode CD. The kernel paniced!
Here is a short description of the hardware I use:
P133 on a Gigabyte GA-586ATE,
Adaptec AHA-2940UW
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: CONNER Model: CFP2105S 2.14GB Rev: 2D4D

Host: scsi0 Channel: 00 Id: 04 Lun: 00
Vendor: PLEXTOR Model: CD-ROM PX-6XCS Rev: 2.05
Type: CD-ROM ANSI SCSI revision: 02

So far everything worked fine under 2.0.36. I thought I it could be interesting for some kernel hackers.
