After 3+ days of uptime, including continuous SMART monitoring (which
without patch triggers an immediate disconnect, and with S=F6rens patch
triggered a disconnect after ~16 hours) and a fair amount of disc =
activity
on both channels it looks like maybe the serialization patch from
Ville-Pertti is enough to make my SATA controller work properly. Of =
course,
it also slows things down, but right now that is better than the
alternative.

S=F6ren, if you have any other patches you would like me to test just =
let me
know.
