hi all...

i'm having a problem with my ncr53810 scsi host and i'm not sure it its
a bug or if i'm doing something wrong???

i have a dell omniplex 590 which has the ncr810 host built-in on the
motherboard and there is only 1 scsi device attached to it (a hard
disk)... all is terminated properly and works 100% under windows nt...

frequently (about every 10-15mins when running X11) my system crashes
and following are some of the errors on my console:


sd0(ncr0:0:0): FAST SCSI-2 100ns (10mb/s) offset 8

ncr0: restart (ncr dead ?)
/kernel ncr0: restart (ncr dead ?)

/kernel: script cmd = 88030000

ncr0:0 error (81:0) (8-a2-0) (0/13) @ (ffd1002c:00000000)
	reg: ca 00 40 13 47 00 00 1f 71 08 00 a2 80 00 0a 02.

ncr0: restart (fatal error).
sd0(ncr0:0:0): COMMAND FAILED (9 ff) @ f1243400.
sd0(ncr0:0:0): COMMAND FAILED (9 ff) @ f1243a00.
sd0(ncr0:0:0): COMMAND FAILED (9 ff) @ f1243c00.

vnode_pager_input: I/O read error
vm_fault: pager input (probably hardware) error, PID 599 failure


...basically the messages repeat each other with slightly different
values many, many times... after this happens, the system does not
freeze (i can still type and run commands (that are in cache)), but the
hard disk is not accessable... so i have to reboot... and then all is
working again until the problem happens again...

this basically makes my system impossible to use, so I will be VERY
grateful for any help....

thanks in advance
m. :(
