IDE breakage with cdrom in 2.5.18+

IDE breakage with cdrom in 2.5.18+

[Udo A. Steinberg]

Hello,

Some code introduced in 2.5.18 seems to have broken something in the
cdrom code. 2.5.19 still has the problem, whereas 2.5.17 seemed ok.

/dev/hde shows packet command errors upon bootup. Any ideas?

Regards,
-Udo.

Just remove (or tweak) the ata_revalidate from the recently added attach method
there and you should be fine perhaps. I will check this
tomorrow later. This doesn't happen with a modularized driver and
therefore the chances are indeed very high that this is the
culprit.

afaic looks "try to detect partitions" lookup that should not had been
done on cdrom :-(
