This output doesn't help -- it's too terse. Please use "pciconf -lvbc"
instead.

Thank you for tracking the issue down to something between roughly
April 25th and April 29th.
Different revisions/models of the ICH9 offer AHCI capability. Does your
system BIOS let you toggle this? If so, I would recommend enabling it
then trying to use ahci.ko ("load ahci.ko" from the loader "ok" prompt,
or ahci_load="yes" in /boot/loader.conf) to see if things improve. Your
CD drive will then appear as a SCSI-esque CD drive (e.g. cd(4) driver
instead of atapicd), so be aware. This would be a workaround for your
issue, assuming it works.
I've CC'd mav@ who has likely committed something that's causing this
issue, but unknown at this time. Relevant cvsweb details which someone
can sift through:
