I ran the command:
atacontrol spindown ad10 60
on my desktop and similar one on my laptop.

In the morning I found that laptop rebooted overnight, and desktop was
still functional, but I suddenly got flooded with the message:

fwohci0: device physically ejected?

then the system froze and had to be rebooted. I never use anything related
to fwohci.

Harddrives are:
ad10: 190782MB <Maxtor 6L200M0 BACE1GA0> at ata5-master UDMA100 SATA 1.5Gb/s
ad4: 152627MB <WDC WD1600BEVT-22ZCT0 11.01A11> at ata2-master UDMA100 SATA 1.5Gb/s

 please don't set your hdds to a spindown timeout of 1 minute! this WILL damage
 your hdds. anything above 15 or better 20 minutes should be ok. keep in mind
 that the spindown value is measured in seconds!
 
 sorry i cannot help you with the other issue. have you encountered it again?
 
 cheers.

State-Changed-When: Tue Feb 15 00:31:23 UTC 2011 
State-Changed-Why:  
This functionality was added to the CAM(4) subsystem. Since the ATA(4) 
subsystem will be obsoleted very soon it's highly unlikely that this 
functionality will be added.
