Comment 57 for bug 84603

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.
