2.5.67: Stack dumps in ide-scsi code

2.5.67: Stack dumps in ide-scsi code

[Eric R. Buddington]

Linux-2.5.67
Asus A7S-VM motherboard with suspected problems (onboard USB, Ethernet
  flaky)
HP 200j CD/DVD writer
Duron 950 processor

While trying to burn a DVD-RW on my HP 200j, a got a rapid series of
stack dumps. I think the initial dump was different, but scrolled
out of the buffer.

Two dumps below repeated (alternating) several times, until hdc (the
DVD writer) was offlined.

If the questionable motherboard makes this uninteresting, that's OK.
I'll have a new MB soon, and re-submit if it still happens.
