Bug#323155: atapicam and 15s delay
reopen 323155
retitle 323155 atapicam delays boot by 15s
thanks
The following patch should fix it. I took the 2s value from a commented like
in /boot/loader.conf. It seems reasonable to me, and I think it should work
with most ATAPI/CAM or real SCSI devices (anyone with a real SCSI can confirm
this?) but I suspect that with some weird devices it's not enough (which would
explain why they set it to 15 by default).
Since this option can be tweaked via /boot/loader.conf, I don't think it's a
problem to hardcode it to 2s in the kernel. Unlucky users with a crappy 15s
SCSI device can change it later.
