There are a few bugzilla entries related to this, one of which (155472) claims that the test kernel in http://people.redhat.com/davej/kernels/Fedora/FC3/RPMS.kernel/ fixes the problem. This doesn't help me as I'm using atrpms kernel modules and so need to wait for an official release. It might help you though. Regards, Chris
