[Bug 577465] Re: dvd / cd drives not handled correctly in 10.04 LTS

[Cymbaline]

I have the exact same problem as Thomas, above.

A few minutes after booting, the CD/DVD drive disappears, never to
return, with the exact same type of errors:

and ad nausem, then the drive is gone.  Aftwards, drive utility still
shows it as being there, but refuses to acknowledge that there's media
in the drive (see screenshot)

wodim --devices returns nothing
lshw -short doesn't show the CD/DVD burner.  

Mine is also a TSSCorp drive.

This started happening after upgrading to 10.04 LTS, no problems on
prior 9.0x versions.

I am still relatively new to Ubuntu/linux, and will gladly run any
traces/reports if told what to run.  Unfortunately I am not in a
position to upgrade to the development release.

Thanks.
