Comment 1 Josh Boyer 2011-09-26 19:37:31 UTC

This appears to have been reported against a rawhide f16 kernel.  Does this still happen with the 3.1-rc6 f16 kernel or the latest F15 2.6.40.x kernel update?

Comment 2 Michal Nowak 2011-10-10 13:26:08 UTC

It's gone with latest 2.6.40.x I have from Koji.
