System hangs with ATAng

I suspect that I have a system losing interrupts from the disk. I get
fairly random lock-ups where the system totally freezes and the disk
access LED is on continuously until I power cycle the system.

It's an IBM T30 with an IBM 40 GB disk. The only thing I have noticed
is that the lock-ups only seem to occur when both ATA busses are in
use. Unfortunately, it may simply be that DVD and disk activity at the
same time simply are stressing the system a bit more.

The DVD is using the ATAPICAM device. DMA is enabled on both the disk
and the DVD. APM is in use. No ACPI. Kernel was built on Oct. 31.
(Maybe it's haunted. :-) )

I have DDB in the kernel, but not WITNESS or INVARIANTS. APM is in
use. No ACPI. I will attach my kernel config file and dmesg.

Any suggestions on how to proceed would be appreciated.
