Doesn't boot on this machine. It hangs after:

30 seconds later, I get something like:

hde: lost interrupt
hde: lost interrupt

The kernel does not recover. Presumably it is a problem specific to my PDC IDE 
controller.

In addition, I've caught another (unrelated) interruptible_sleep_on bug in msp 
audio for my v4l WinTV PCI card. I couldn't get the call addresses written 
down, but it goes something like..

interruptible_sleep_on 0xe9/0x120
default_make_function ..
msp_3400c_setbass ..
msp_3410d_thread ..
kernel_thread_helper 0x5/0x10

I guess this is something the v4l2 maintainer needs to look at.
