I think whatever is broken in my FEC code is exposing a different bug
in some timeout code that is not normally run. Something to do with
the swap thread being unable to get to the swap device maybe?
Can anyone tell me where this Oops is coming from? It is the same oops
as the previous one, but the stacks are different.
I am getting it after a random number of retries of:
nfs: server 192.168.1.4 not responding, still trying
