Issues[edit | edit source]
Linux[edit | edit source]
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 > /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.
