Comment 1 Mikko Tiihonen 2011-08-30 12:49:49 UTC

this still occurs in kernel 3.1.0-0.rc4.git0.0.fc16

Comment 2 Mikko Tiihonen 2011-09-24 08:36:26 UTC

This seems to be fixed in kernel-3.1.0-0.rc6.git0.3.fc16.x86_64.

The warning no longer appears in system logs whereas in 3.1rc5 it occurred dozens of times every day.
