freebsd-skq/sys/dev/ata/atapi-cd.c
sos 24ced90f97 Fix the problem with certain ATAPI commands on AHCI devices. 
Revert the probe in atapi-cd.c to the old usage now its fixed on AHCI.
THis change also fixes using virtual CD's om fx parallels.

Still leaves the GEOM problem of telling media vs device access apart in the access function.
