[parisc-linux] scsi problems on a 720

[Riccardo Mottola]

Hello,

I tried to install linux (specifically gentoo, but the same problem appears
using debian too) and had mysterious kernel freezes.
The guys at gentoo-hppa told me to ask here since they didn't know further.

I have a 9000/720. The computer runs without problem using HP-UX.

I have added a second drive, an IBM, 2GB. Using mediainit from hp-ux reports
no errors.

If I try to put a new filesystem like ext2 or ext3 on the big (about 2gb)
partition, the kernel will freeze while running mkfs. Frreze means no
output, no error messages. The heartbeat stops.
Putting reisers seems to work, but after downloading  and  uncompressing a
big file, i get the same error-less kernel freeze.

this is what dmesg reports:
3. Cobra Core SCSI (10) at 0xf0825000 [2/0/1], versions 0x4, 0x0, 0x71

and this is seen in lsmod:
