 Disabling the standby timer "solves" the problem. But the documentation 
 of smartd states, that it should be able to work with drives in standby. 
 So either this doesn't work with netbsd or it just doesn't work with 
 ahcisata.
 Another thing: My previous system had drives on a piixide and when the 
 drives woke up from standby, the kernel did not log a error message. Now 
 I get errors like these from time to time:
 
 Jan 2 02:03:02 zork /netbsd: wd3e: device timeout reading fsbn 597712576 
 of 59$
 Jan 2 02:03:02 zork /netbsd: ahcisata0 port 3: device present, speed: 
 3.0Gb/s
 Jan 2 02:03:02 zork /netbsd: wd3: soft error (corrected)
 
 
 Is this something to be fixed or is piixide just more tolerant?
