Comment 12 for bug 544548

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
