>Description:
When I use ataidle to put a disk in standby or sleep mode (ataidle -s or -o), trying to access it again hangs the system.  I might expect it to hang briefly while the drive spins back up, but it never recovers.  Even numlock on the console doesn't work anymore.

ataidle -i doesn't cause a problem.  On the other hand it also doesn't seem to spin the disk down.

This is possibly related to kern/117421 since it's a similar symptom on the same hardware.

Output of dmesg in verbose mode:

cam: using minimum scsi_delay (100ms)
