Ok, after much head-scratching and bisect-powered reboots I have
disproved for myself that this is a kernel issue.

Instead it's some weird interaction between certain BIOS settings on my
motherboard (ASUS P5Q Premium) and my SCSI controller (HP SC11Xe,
FusionMPT based) I use for tape specifically when there are no SCSI
devices on the bus. Skipping the mptspi module, or connecting a SCSI
device causes the problem to go away, ditto changing some settings in
the BIOS that cause IRQs to be allocated differently.
