There may be a change, but - espacially since your dmesg shows a PATA device - I
don't think the ATA driver is it.
6.2 7-CURRENT (SEP snapshot iso) thru 7-BETA1, plus 8-CURRENT in i386 and AMD64
are happy with real or virtual CD's here legacy IDE PATA, *with QEMU*.
And that on two MB with reportedly problematic BIOS / chipset IDE/SATA settings
(Asus P5K, Gigabyte GA G33-DS3R).
Ergo, I'd suspect Parallels is unhappy with something in between itself and the
You might do a quick install of Qemu - even if it is not on your long-range plan
- just to see if the problem persists.
