is seen on the screen.

Created attachment 131994 [details]
/var/log/messages starting near the boot with new kernel
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 bug has been placed in NEEDINFO state.

In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.
This machine is now running FC6 and with all updates current I no longer have
this bug. Relevant /var/log/messages lines are:
Nov 21 10:42:10 gestalt kernel: ACPI: bus type pci registered
Nov 21 10:42:10 gestalt kernel: PCI: Using MMCONFIG
Nov 21 10:42:10 gestalt kernel: Setting up standard PCI resources
Nov 21 10:42:10 gestalt kernel: ACPI: Interpreter enabled
Nov 21 10:42:10 gestalt kernel: ACPI: Using IOAPIC for interrupt routing
So this BZ can be closed.
