Hi,

On 2 March I upgraded my ASCI kernel image from 4.9.0-6-amd64 from
4.9.0-12-amd64.

I've not noticed any problems but I've not been running anything CPU
intensive. My processor is a AMD Phenon II X4 910e.

What I did note is that when I did the upgrade it also brought in
modules firmware-linux-free (3.4) and irqbalance (1.1.0-2.3).

Could the problem be in irqbalance (1.1.0-2.3)? I upgraded from 4.9.0-
6-amd64 so I can't say if this version is new since 4.9.0-11-amd64?

"Irqbalance is a daemon that monitors the cpu load created by various 
interrupt sources and attempts to distribute that load over the 
available cpus in your system in an attempt to better balance system 
latency and throughput."
