ide-scsi hang

Using xcdroast with ATAPI cdrom and ide-scsi drivers I hit
system hangs a few times. Either when copying the disk or when
verifying the copy. The only way to recover from these hangs is to
hit the "reset" button.
Xcdroast is just doing a sequencial read from the disk. Hangs
are not persistent but they happen more often with certain
disks than with others.

This happened on Linux-2.1.110 compiled for SMP but running on
single processor. I experienced similar hangs with other recent
2.1.xx kernels which were fixed by recompiling the kernel without
SMP support.

Ingo, I remember that you had a tool to assist in tracking
such hangs. Where can I find it and how can I use it?
