Re: [BUG] ide dma_timer_expiry, then hard lockup

So what do you suggest? (I could buy an alternate ide controller,
and hope that goes away, or just buy a different hard drive. But
that's beside the point).

The DMA timeout itself could be all sorts of things - crap driver, crap
hardware, PCI bus contention, noise, problem disk, phase of the moon.

I can prepare a patch, but only with a lot of guidance. I can test 
& debug, I'm highly motivated just right now ... 

If you've got a nice repeatable problem please try using the libata
driver. That handles the error paths differently and doesn't try a FIFO
drain which might matter in this case I guess.
