You could try forcing the drive to a lower speed to see if taxing the
hardware less will avoid triggering the problem.
Make a file /etc/modprobe.d/local.conf and put the single line
options libata force=1.5G
in it. Reboot. If it works, you can then try with 3.0G instead of
1.5G.
Thanks, I will try that and see if it helps, but it seems a lot like a
hardware problem. This motherboard is getting to be a few years old,
and has been working fine up until now, it just started behaving like
this a few days ago.
I'm investigating new motherboards now, since I heavily suspect that is
going to be what I'll end up having to do.
The drives/controller are not heavily utilized when this happens, the
machine is just churning along with low load. I always have gkrellm
open, and there is never any hint that utilization has anything to do
with this.
