Over a month ago, I posted a timeout problem I was having with my
symbios controller and fujitsu drive, on 2.2.7R
I have now upgraded to 3.0R and the problem although different, still
remains. I was advised at the time that the problem would be easier to
diagnose under 3.0, so here goes...
I can force the problem by performing a "tar -cf /dev/null /usr". After
a short while disk activity stops. Then after a further 70s-80s the
following messages appear:
ncr0: timeout nccb=0xf09a4400
ncr0: timeout nccb=0xf09a4800
ncr0: timeout nccb=0xf09a4c00
ncr0: timeout nccb=0xf09a3000
ncr0: timeout nccb=0xf09a3400
ncr0: timeout nccb=0xf09a3800
A couple more appear later, then the whole lot repeats every 60s-70s.
The last time I tried this, it took four attempts before it would pass
fschk without hanging again. On the second attempt the following
messages were generated:
ncr0:0 ERROR (0:5) (8-0-0) (f/9d) @ (script 7ec:190003fa).
ncr0: script cmd = 89030000
ncr0: regdump: da 00 80 9d 47 0f 00 0f 03 08 80 00 80 00 01 02.
ncr0: have to clear fifos.
ncr0: restert (fatal error).
(da0:ncr0:0:0:0): COMMAND FAILED (9 ff) @0xf0857400
Dmesg.boot is attached in case it may be of use.
ncr0 is a symbios logic v4.0 pci scsi bios pci rev 2.0,2.1 pci-4.11.00
53c875 fast20 wide scsi, and da0 is a fujitsu M2949E-512 HDD (about 8.5
Gbytes). The disk is divided into almost two equal slices, with FBSD in
the top 4G.
I understand that in future I should use Adaptec scsi cards and Seagate
or IBM disks. Meanwhile, however, any help with which bit needs fixing
or throwing away would be much appreciated.
Thanks,
