The ktrace output was not so helpful yesterday. The error was
reported when trying to open /dev/xpt0 like this:
60742 cdrecord CALL open(0x8067a2b,0x2,0xbfbfdf54)
60742 cdrecord NAMI "/dev/xpt0"
60742 cdrecord RET open 3
60742 cdrecord CALL break(0x8081000)
60742 cdrecord RET break 0
60742 cdrecord CALL ioctl(0x3,CAMIOCOMMAND,0xbfbfdf38)
60742 cdrecord RET ioctl 0
60742 cdrecord CALL close(0x3)
60742 cdrecord RET close 0
60742 cdrecord CALL write(0x2,0xbfbfe170,0x3e)
60742 cdrecord GIO fd 2 wrote 62 bytes

I guess it requires "device pass" in the configuration to be useful.
