I can't remember exactly what was the panic (it happened when probing ATA
drives). I probably compiled NetBSD 3 kernel with wdc_mb.c revision 1.27
and that kernel booted without panic.

Without hooks and NOIRQ flag kernel prints several intr_dispatch: stray level
71 interrupt errors and panics:
panic()
intr_dispatch()
intr_glue()
wdc_ata_bio_intr()
