I don't think it has anything to do with ISA. I've had similar problems on a PCI-only system (actually, PCI+EISA motherboard with no EISA cards) with no ATA devices (disks, CD-ROM and streamer are all SCSI). Considering that backing out rev 1.14 of ithread.c eliminates the panics, and that that revision is supposed to enable interrupt thread preemption, and that the crashed kernels show signs of stack smashing, I'd say the cause is probably a bug in the preemption code.
