--- Comment #4 from Ilia Mirkin <imirkin at alum.mit.edu> ---
I doubt this is it, but this patch only made it into 4.1.13:

https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=930a50a45963c8da0a27fbee73ae462d8ea54aca

The manifestation of that bug was different though, so ... probably unrelated.
Wouldn't hurt to update though.

There have also been slight updates to the ctxsw fw in kernel 4.4, so you could
try 4.4-rc8 and see if the issues remain. (Also the driver got a substantial
refactor/rewrite in kernel 4.3.)

Either way, please check on latest to see if issues persist.
