I would like to pre-apologize if I am posting this to the wrong list. I
am running FreeBSD 4.1-STABLE on x86 with this Adaptec 3960D Ultra160 SCSI
controller using an IBM DDYS-T09170N Ultra160 disk. The machine locks up
weekly on any heavy load. It was crashing when the vm system would get
stressed so we added more memory and now it is only crashing with the
filesystem is stressed (I think).
One of the problems is that the Ultra160 disk (the IBM one) is not coming
up at 80 MHz only at 40 MHz:
da0: 80.000MB/s transfers (40.000MHz, offset 63, 16bit), Tagged Queueing Enabled
I'm not sure why that is happening because the SCSI adapter in the bios
detects it and shows it listed as operating at u160. I figured it could
be a driver issue so I updated from 4.0 to 4.1 and that seemed to not help
too much.
Here is the debugger output from today's crash:
(da0:ahc1:0:6:0): Invalidating pack

(on and on)
I'm not much of a BSD genius, any help would be very appreciated.

[Q]: Hey, do they test this stuff before it's released?
[A]: Sure they do... "It compiles, it's ready!"
