port over some workarounds from dragonfly, or just figure out what is causing 
enough disk access to trigger this behavior and use a different machine for it

Greetings,

Any thoughts as to how to get around this - it's only been up for a few 
days.  Rebooting my home router every 24 hours is not spouse endearing behavior 
:)

here is the key error message. it means your whole ahci disk has disappeared 
(and anything you can still run is happening from cache.)

--
ahci0: stopping the port, softreset slot 31 was still active.
ahci0: failed to reset port during timeout handling, disabling it
--

likely a reboot will fix it. this is a known problem with ahci driver and intel 
ahci controllers.

the "failed to reset port" and "softreset slot was still active" problems 
become really obvious once you start maxing out disks on an ahci controller 
with a softraid array. they rarely present problems in normal use! but, the SSD 
sata drive may evoke different behavior for some reason. i think continuous 
runs of iogen over a RAID1 array might bring out similar issues all by itself, 
even with regular hard disks 

dragonflybsd's port of openbsd's ahci driver has incorporated several of 
workarounds for problems directly related to this. (reset this when that 
happens, etc..) that might be a good place to start looking, if you can easily 
reproduce the problem then you would know quickly when a ported fix from their 
driver has helped.
