Comment 40 for bug 501207

I'm still getting this problem.

I'm running:

Linux gurgle 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 22:02:19 UTC 2010 i686 GNU/Linux
Mobo: Asus P5B Deluxe
CPU: Intel Core2 duo E6400
DVD: Pioneer DVR-218L (SATA)
The DVD-RW drive is plugged into SATA port 5, and detected as ata3.00 / scsi 2:0:0:0

I'm pretty sure this is related to bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/228624.

This bug is reproducible, but there is a twist. I have a dual boot machine. Yesterday I booted into Windows XPSP3 (32bit) and used the drive to listen to a couple of CDs, then I rebooted into Lucid and everything worked.

Tonight I boot direct into Linux and no potatoes. I'll try the boot-into-windows thing a few more times, and see if there is anything I can find from that perspective.

hdparm reports that it's set to UDMA5, but various specsheets indicate that it's only UDMA4 capable?

$ hdparm -i /dev/sr0
