FlashPoint and Kernel panic -- problem

> I have FlashPoint SCSI adapter with 3 disks and 1 CD on it.

Which model (controller, harddisk and CDROM) ?

I have a FlashPoint KT-950 with 2 IBM DCAS 4 G (UltraWide) and an old
Quantum Maverick 516 MB (FastSCSI) and a Plextor 12Plex CDROM. The IBMs
are connected to the 16-bit-bus, the other devices to the 8-bit-bus.

I've reduced the Quantum speed to 5 MB/sec, SCSI ultra mode is disabled.

This runs flawlessly under Linux 2.0.33 since 4 months, I've never had
any failure with this box.

I've no definite answer to your failures, but possible problems can be:
- old devices (SCSI-1, speed to high)
- ultra mode and cable length
- passive termination (use active in ultra mode).
