Did you try unmasking the interrupt on your hard drive (hdparm)? Of course
this isn't an issue if it's SCSI, but for some reason, at least still as of
2.2.15, the default for the driver is to have it masked, to not use 32 bit
xfers, and to not use multi-sector xfers, even though modern drives and
chipsets would suggest that these could safely be the defaults these days.
IMHO. Andre? These would all help this problem, unless this is some "other"
bug.
