I'm able to consistently reproduce the lockups, and currently run on
non-SMP kernel because of them. Would you like any aspect of my
configuration in detail? It is completely the same except the SMP-ness of
kernel.
Here're some for starters:

It might be significant that all lockups seem to coincide with SCSI CD-ROM
or tape activity; that is, it is perfectly possible that if I had none of
these devices but only harddrives, there would be no lockups.
