There are two distinct issues.

-- ide driver locks up on hpt366+new maxtor disk under heavy
i/o load. I was able to copy 60GB from old to new disk without a
problem; however, raid reconstruction locks it up, maybe after 5-15
seconds.
This probably is "hardware related"; its something that the new
hard drive does. Given that its being sold at a big discount, it
may even be that the sellers know that this is a crappy disk. :-)
All I want is some way of resetting the disk, and continuing on.
It would be useful to see hdparm --Istdout output for *both* disks.
I'm stalled in debugging; I'm not sue what I'm looking for.
Sergei, do you think that testing the drive with DMA disabled may
tell us something new?
Not sure. I'll try to come up with a patch esetting the state machine in
dma_timeout() method (following Alan's idea) -- HPT366 regs are different
enough to use the one for HPT370.
Thanks,
Bart
