Ok, we had some luck. Here's the backtrace and attending dmesg
output. The filer has been doing failover, but it has not gone
into a failed state...so, the system *should* be able to reconnect.
We have the system in the failed state now and will leave it that way
for a bit in case you have some commands you'd like me to run.
Aside from the hung cifs processes (anything accessing those mounts
gets into the D state), the system seems fine.
