A workaround has been found: unload the wired ethernet module before
entering the WPA password. Works for me.
sudo rmmod atl1c
This seems crazy: likely a bug in the Attansic driver. Part of the
kernel. But I cannot figure out what to add as a "project" at the top
of this report.
Here's lspci -vnn output:
