It just doesn't work :)
Transfers stall and here is the kind of message I get:
hdb: lost interrupt
hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdb: drive not ready for command
hdb: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdb: drive not ready for command
