If I can find the time tomorrow morning, I'll leave parport_pc commented out
of modprobe.conf and see if something else pops loose. I don't use the
parallel port, but I try to keep a fairly robust config for noticing bugs.

Hi Mick,

Can you please try the patch below from Linus (or -git2 tomorrow) and confirm that it fixes it for you?

Hi Cal,

I'll give that a go in about 30 minutes and report back, hopefully on *rc4-* ;) . I'm not sure I'll be around in the morning so will apply this to today's and see.
