When it's mucked up, I get endless messages as follows, and processes accessing the drive remain in uninterruptable sleep for several minutes.

I've tried reloading the kernel modules (cdrom, ide-cd) and issuing "hdparm -w", both of which have no effect. Momentarily ejecting the disc sometimes allows it to work for a bit, but rebooting seems to be the best workaround. I see in the archive that there have been posts about these error messages, but I didn't find any replies that address them. Is there a faq somewhere that covers this? The kernel is the redhat kernel-smp-2.4.18-24.8.0 release. The mainboard is an Asus P2B-D (IDE interface: Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 1)). Any ideas? b.c.
