Yes it would... :o) I think I've got it here.

The new error handling code spinlocks the IRQ which cause the lowlevel
parport driver to choke. This patch unlocks, allows the lowlevel driver
to do it's probes, and then relocks. It could probably be more granular
in the parport_pc code, but my own home tests show it to be working
fine.
