This is a dual PIII system on an Intel L440GX+ motherboard. The
configuration at the time of this issue was two SCSI HDs, boot
device an LDV on channel A and second disk on channel B, along with
two IDE drives attached to the onboard controller.
I could not keep the system running well enough to run send-pr
directly, so I have attached the boot log that shows the configuration
during boot without the SCSI disks attached (attaching the boot disk
under 5.1 causes the problem, since it sits on the A channel). This
is the best I can do...

>Description:
When I attached an LVD device to the A channel of the onboard SCSI
controller (Adaptec AIC7896/97), the system generated a large number of
these errors, particularly when under a heavy I/O load. Each error
message was accompanied by a kernel hang ranging from a few seconds
to several minutes.
da0: Timedout SCB already complete. Interrupts may not be functioning.
This also occurred on da1, which is attached to the B channel, but only
if a device was also connected to the A channel.
>How-To-Repeat:
Attach SCSI device to the A channel and boot, then run an I/O intensive
process.
