:Is that correct for it to still report SATA150?

The UDMA/PIO stuff might not be adjustable if its a SATA controller
emulating an IDE controller.
I think what is happening here is the NATA driver is detaching the
drive and destroying the related dev structures before it finishes
cleaning out any pending I/O's, so then when it tries to ad_done()
the request it winds up blowing through dead structures.
There must be some error messages reported in the console output
that we haven't seen yet. You can try:
dmesg -N kern.0 -M vmcore.0
And see if any other messages above the 'ad6: FAILURE' message are
present.
