Are you still able to reproduce this with 3.16.0?

I updated my 13.1 system to use the 3.16.0 kernel on a VM with a parallel port and could not reproduce it.

Hi Jeff; I am AFK from this particular system at the moment and no remote access to it ATM. will report back when possible if still reproducible. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
