Hello !
I got a fourth crash on our cache server with same error message. I have no
clue what I must do to avoid this scene. For first crash I got replies which
suggest control scsi termination and cable quality. I have controlled
everything and changed cable... but it happens again.
Crash is related to scsi subsystem:

I use ccd on this particular machine. After working two or three weeks
flawlessy, machine crashes with same error messages. Scsi hard disks lights
are on and I can't access ccd stripe set. Machine works, because system
partitions are on the other disk, but squid are dead. I can't live with that,
machine is dedicated to www cache. Scsi controller type is ASUS PCI-SC875,
scsi BIOS version 4.03.
