Yeap, I'm aware of the problem. That's why the driver is marked HIGHLY
EXPERIMENTAL. Maybe I should change it to broken. :-( Anyways, one of
the known problems is mishandling of LBA48 commands which is cause of
timeouts and wrong md5sums on large disks. I just couldn't find any
time to work on it in recent weeks. Please be patient a bit. I'll get
back to sata_ini162x in a few days.
