cam_xpt.c:
Add quirk entry for a Samsung drive that doesn't like experiencing
the queue full condition.
Bump the timeouts for all probe activities to 60s. We don't know
what the seletion timeout (or equivelent on other mediums) is
for controllers, which can make the transactions at the tail
end of a parallel probe take a while to complete. The DPT
seems to be a card that takes a long time to see a selection timeout.
cam_periph.c:
Don't call a device "gone" after a single selection timeout. We
need to come up with a better policy. Until that time, you'll
have to manually re-scan a bus via camcontrol for the system to
decide that a device is really gone. This should give devices
experiencing temporary insanity to escape death.
