I have a multiboot environment on this machine.
Then rather try to install the old x86-64 kernel on Leap 42.2 system and test
with it. Btrfs might be a problem with the old driver, though...
In anyway, if 3.12.x shows the problem, it's probably a regression since long
time ago. Then the best would be to contact with the upstream dev. According
to MAINTAINERS file, parallel port maintainer is:
