[parisc-linux] System hangs after SCSI problems

[dub@latnet.lv]

Hi,

I run Debian vmlinux-parisc-2.4.20-32-smp on K210. Not recently I faced a
strange hang situation. Host stopped responding both from network and console, 
ethernet port remained up on link level. In syslog.log and kernel.log I see scsi
problems.

After restarting all disks are OK (one of mirror partitions was resynced manually). 

Thank you in advance for any comments!

BR,
Dub
