[Bug 544548] Re: Kernel doesn't detect media in CD/DVD drives

Hello,

I'm using Lucid with kernel 2.6.32-22-generic and have this same
problem.

I have two devices attached to ATA1:
ata1.00: ATAPI: LITE-ON DVDRW SOHW-1633S, BS0H, max UDMA/66
and
ata1.01: ATAPI: Compaq  CRD-8484B, 1.04, max MWDMA2

I haven't played with ata1.01 (the Compaq CD Drive), but definitely
there is something flaky going on with the DVD drive (ata1.00 LITE-ON
DVDRW)  The drive sometimes recognizes blank media, sometimes it
doesn't.  (Although the dmesg output suggests both drives are flaky)

This issue has only occurred for me since upgrading from Ubuntu Karmic
to Lucid.  My dmesg log snippet is below - Let me know if I can help at
all.

Kind regards, Iestyn Guest
