Hi,

I am seeing ... issues with the optical drive (hda) under 2.6.36. I
can't mount disks:

[root@PowerMacG5 ~]# mount -r /dev/hda /mnt/cdrom
mount: /dev/hda already mounted or /mnt/cdrom busy

The log has:

[  239.922268] hda: irq timeout: status=0xd0 { Busy }
[  239.922485] hda: possibly failed opcode: 0xa0

eject hda will hang ... longer than my patience.

At first I thought the drive was going south. But I don't see this (at
least so far) on 2.6.28.

Thanks!

kevin

Do you see something similar if you use the new libata based driver
(macio-ata) instead of the old IDE driver ?

It does look like the drive itself is crashing tho. Maybe something the
IDE CDROM driver does upsets it...

Cheers,
Ben.
