[BUG 2.6.0test2] unwanted ATAPI requests during boot

[BUG 2.6.0test2] unwanted ATAPI requests during boot

[ffrederick]

Hi,
        2.6.0.test2 does the following when no cd inserted during boot:
2.6.0test1mm2 was ok.

        Problem could come from bio changes (ll_rw_blk).When tracing make_request, I've got neverending polling there...

Regards,
Fabian

hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x54
end_request: I/O error, dev hdc, sector 0
ATAPI device hdc:
  Error: Illegal request -- (Sense key=0x05)
  Invalid field in command packet -- (asc=0x24, ascq=0x00)
  The failed "Start/Stop Unit" packet command was: 
  "1b 00 00 00 03 00 00 00 00 00 00 00 00 00 00 00 "
cdrom: open failed.

Has nothing to do with bio changes, and you would never see this request
in __make_request since it's internally generated by ide-cd.

I'm guessing you have a pop-up type tray?
