Issues

Linux

The module atl1c drives the onboard Atheros ethernet adapter but will use up all the available CPU. This happened on the Linux Kernel used by Ubuntu (3.13.0-24) while running ClonezillaAlt. Removing it is not an option since it will kill the networking.

You can verify this after booting into linux by running the following a few times. 

echo l &gt; /proc/sysrq-trigger
dmesg | tail -n 50

The kernel worker, kworker/x:y (where x and y are random based on which CPU core is running the module), will use up 100% of the available CPU of one core.
