The patch available from there was briefly discussed in February:
Yes, it seems to help. If I boot up and modprobe the driver with
toshiba=1, everything looks fine (I have no firewire devices to test
with). If I modprobe it with toshiba=0, the system gets sluggish for a
second then IRQ 11 is disabled. I had to update the patch though,
