Thanks, could you also try a patched 4.0_RC5 kernel
to see if the similar patch works for a recent source?

I've never tried this kernel before, so I don't have anything to compare
to. But it hangs after displaying...
kbd0 at mainbus0
and stops. So I'm not sure if it's even started the wdc probe or not.

Oh, wait a minute.
I left it there for at least 60 seconds or so, and it eventually carried
on until it hit...
scsibus0: waiting 2 seconds for devices to settle...
and it's pausing again.

Grrr, yes, it did continue but it took about 5 minutes and is now stuck
at the scsibus0: waiting 2 seconds for devices to settle.
So, it didn't crash either as it did in the 3.1 kernel.

Hmm, is "wdc0 at mainbus0" probed properly on both stock
and patched 4.0_RC5 kernels? Could you post dmesg?
The hangup might be caused by spurious interrupt storm,
but it should be handled in another PR..

Ah, it's detected fine with the patched kernel, but not at all with the
stock kernel.
