>Description:
Inter Pentium-133 with two 2940 PCI SCSI adapters
first is a UW with the system disk, no heavy load, no problem
second controller is a narrow one with 4 x 2GB Micropolis 4421AV disks
we use it as our news server but it isn't really loaded as yet
still we write/read/erase many files on those disks and some of them 
are really big (think of alt.binaries.....) 
from time to time it reboots with the following in the syslog

Apr 17 07:00:49 callisto /kernel: sd4(ahc1:4:0): SCB 0x1 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0
Apr 17 07:00:49 callisto /kernel: SEQADDR == 0x6
Apr 17 07:00:50 callisto /kernel: sd4(ahc1:4:0): Queueing an Abort SCB

  
I read that FreeBSD had this problem before but I thought that this has been fixed 
in release 2.2.1 - stable
