Hi,
I just had a look at the current doc/m68k-linux.txt file.
DEBUG: raw_scsi: got command byte 00 (6/6)
WARN : HDC: *** Strange REQUEST SENSE ***!
DEBUG: raw_scsi: data in 22 bytes waiting
Am I right that Linux requests a 6 byte response? This is not strange, but
perfectly legal, because Linux may just have reserved a 6 byte buffer for
the response because it does not need more bytes. I suggest to remove this
message.
What I actually stumbled upon is this:
DEBUG: raw_scsi: data in finished, 22 bytes: status phase
DEBUG: DMA initiator recv PC=001c40ee
DEBUG: SCSI BUS reset
Where does the 22 come from? The message looks as if Hatari tries to send 22
bytes, even though a maximum of 6 was requested. If this is the case it
explains the subsequent bus reset and the SCSI boot failure.
Have these messages been recorded with a binary based on the current
Hatari sources? I don't think that with the latest sources Hatari sends
22 bytes when only 6 are requested, but maybe I am missing something.
Best regards
Uwe
