Hi,

I was asked if it made a difference if I warm-booted from Windows.
Curiously enough, it does.  Cold-boot or warm booting from Windows will let
me see the disc that is in the drive.

When I do a dmesg, I do not see any error messages like "atapi.1.0: unknown
phase" or any other error messages for that matter.

The boot does a noticeable pause (10-15 seconds) when it comes to the
secondary IDE card, but not for the primary one.  It then pauses again
(about 10 seconds) before the messages for the CD-ROM drive.  Finally, if I
have cold booted or warm booted from Windows, I get a messages indicating
that I have a 120mm disc inserted in the tray and that it is unlocked.  If I
warm boot, I do not get that message at all or any variant.

I have made sure that the disc was fully spun up (and then some) before
trying to mount.  No difference.  For grins I did try it while it was
spinning up to see if there was a difference.  I get a message telling me
that the tray is open if I have booted in verbose mode (-v).

Could this be a kernel option issue?

Any other thoughts would be appreciated...

Jim
