Ok: I rephrase my question:
Could it be that my HDD behaves strangly (i.e. doing
hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: no DRQ after issuing MULTWRITE_EXT
ide0: unexpected interrupt, status=0x80, count=1
ide0: reset: success
) sometimes when rqsize is set to 65536 altough I only do PIO transfer?
