[Bug 84603] Re: Hard disk I/O randomly freezes when hald is running and optical drive is empty

My problem began after a Feisty update as well.

Try booting into recovery mode and running e2fsck on each partition. 
Then add the kernel options acpi=off pci=bios That seems to have got my 
system working again. I did some tests last night and could boot with 
acpi=off but without the option I had problems. I have also noticed some 
hard disk corruption now as well. The same disk worked with no problems 
when I booted using an old knoppix disk. So I conclude there is a 
problem somewhere between the libata driver and the hardware.
