This isn't actually an Oops, it's a WARN_ON, which isn't as severe as a full Oops. Strange that the fix isn't upstream yet. It's so simple. I've applied the patch to 11.3, 11.4, and master. -- 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.
