Oops using ohci1394 on 2.4.10-ac4

[Tony Hoyle]

I've been trying to get my 1394 card working on Linux...  It's possible
this card (D-Link DFW500) isn't supported, but it probably shouldn't oops
:-)

No devices are connected to the card at this point.  Booted into the
console.  SMP kernel with noapic,nosmp to eliminate smp bugs...

testlibraw gives:

spock:~# testlibraw
