May 16 14:20:03 nata kernel: end_request: I/O error, dev 03:0c (hda), sector 0
in the syslog. The patch below makes ide_open fail in this situation.
(Maybe the surrounding `if (drive->media == ide_disk)' is too
cautious - I have not thought about what other IDE devices there
are, and what meaning the minor could have for them.)
