i've stumbled over a problem with ATA_CAM. when i accessing my dvd-drive i'm
not able to access any other cam members (ada* e.g.).
when i issue the following command:
`cdrecord dev=2,1,0 blank=all'
binaries such as ls, top or vmstat simply stall until cdrecord finishes.
this is the output of `camcontrol devlist -v':
