Same message had been seen on a Asus P5DL2 mainboard with Intel Dual Core 2.8 processor, except that the machine doesn't boot at all after the message that it has loaded the kernel.
I am also seeing the same problem on an Asus P5AD2 after updating to kernel 2.6.17-1.2174_FC5. Was working fine under default FC5 kernel 2.6.15-1.2054_FC5.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) 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.

This machine is now running FC6 and with all updates current I no longer have this bug.
