please upgrade to the latest errata kernel and try and reproduce this. (Better yet, theres a work-in-progress errata kernel at http://people.redhat.com/davej/kernels/Fedora/FC4/ which contain a number of as-yet-unreleased fixes).
This is a mass-update to all currently open kernel bugs. A new kernel update has been released (Version: 2.6.15-1.1830_FC4) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem.
