I have a couple of foxconn netboxes that have SD slots that the system
configures as da0. Starting with FreeBSD 11 we see a wad of syslog
messages from devd every few seconds:
Aug 29 16:57:39 xxx.lbl.gov devd: Processing event '!system=CAM
subsystem=periph type=error device=da0 serial="20090516388200000"
cam_status="0xcc" scsi_status=2 scsi_sense="70 02 3a 00" CDB="00 00 00
00 00 00 " '
Aug 29 16:57:39 xxx.lbl.gov devd: Pushing table
Aug 29 16:57:39 xxx.lbl.gov devd: Processing notify event
Aug 29 16:57:39 xxx.lbl.gov devd: Popping table
This is apparently because the slot doesn't not contain media. We don't
use SD cards with these systems so I tried adding:
hint.da.0.disabled="1"
to /boot/device.hints but /dev/da0 is still present after a reboot.
Where am I going wrong?
