Hi there,
I'm running 2.1.0-R on a Compaq Prosignia 300 (it wasn't my idea! :)
I'm using the machine's on-board SCSI host adapter (NCR chipset), and I've
been experiencing intermittent problems for some time now. At apparently
random times, the SCSI subsystem would just appear to enter an unstable
state, resulting in the following sort of messages flooding to the logs:
Oct 29 11:00:38 asterix /kernel: ncr0: have to clear fifos.
Oct 29 11:00:38 asterix /kernel: ncr0: restart (fatal error).
Oct 29 11:00:38 asterix /kernel: sd0(ncr0:0:0): COMMAND FAILED (9 ff) @f0e7d000.
Oct 29 11:00:38 asterix /kernel: NOT READY asc:4,1
Oct 29 11:00:39 asterix /kernel: sd0(ncr0:0:0): Logical unit is in process of becoming ready
Oct 29 11:00:39 asterix /kernel: , FAILURE
... etc. This is often accompanied by a bit of binary junk written to
/var/log/messages. Once or twice syslogd even core dumped.
Yesterday I tried to do a df on my swap partition (/dev/sd0s1b) - don't ask
my why - and the system crashed immediately; blank screen followed by the
BIOS. I tried it again a few times. Sometimes it would have no effect,
sometimes I'd get failures like those above before a crash, and sometimes an
immediate crash.
Note that I ran df as a normal user, not root! :(
Any ideas would be appreciated.
Some info on the SCSI subsystem:
