Not sure if this is a known problem or not, but under CURRENT (synced
on 9/20), the kernel fails to boot from a raided disk. If I break the
raid array (or even just yank one of the disks and let the controller
think the array is degraded) the kernel boots just fine. When the
array is built, I get the following lines right after probing npx0:
(probe0:0:0:0): CCB 0xf875a07c - timed out
With dpt_scsi 1.14, this error would print about 5 times then panic
with a trap type 12 at
_camq_insert + 0xf movl %ecx,0(%eax,%edx,4)
With dpt_scsi 1.15 it appears to just hang after the print (or maybe I
didn't wait long enough)
Heres some information on the system, let me know if I can provide
anything else:
The system is a single cpu PII-350 without SMP or Softupdates. It has
a PM2144UW with raid module and 16MB cache, with 4 disks attached and
1 tape drive. Only 2 of the disks show up in the dmesg below as I
have taken the others offline since they normally constistute the
mirrors (raid-1) of the two below. The scsi cables/terminators on
this system are top-notch, and it has worked fine with the old scsi
system for a few months. It does have a wd disk, but that is not
booted from, only used for an amanda dump disk.
dmesg output (from when the array is broken and it can boot):
