I just upgraded from edgy to feisty and with the kernel at 2.6.20 I still get this problem, even with a cd in the cdrom drive.
The drive that hangs up is my second hard disk drive which is an ata drive with a sil based sata to ide converter SYBA SD-SATA-IDE, which has been working fine in edgy. The first drive is a native sata drive and seems to work fine. If I boot with my previous (edgy) kernel 2.6.17-11-generic it all works fine, as it did under Edgy. Even though my dvd drive is a TssTcorp, but not the one mentioned above, I believe this bug is in the kernel, and is quite serious. Although it is odd that if I boot in single user mode, the drive does not give these errors, so it could be something in hald or another daemon (maybe smartd?) is interacting? I even installed the latest stable kernel too 2.6.21.1 and get the same error. For now I'll continue to use the edgy kernel, as it seems quite stable.
