I have a system with an ECS 480M motherboard, AMD Athlon 64 3500+, and SATA HD. After upgrading my FC4-x86_64 install to FC5 via DVD, on boot, the initial udev startup failed (including the attempt to background the service). I was forced to reboot, but the system no longer goes through POST. That is, the initial video card check runs, then the BIOS header shows (copyright, version, and main processor listing), but no memory check is run and the normal setup / boot keys (DEL or F12) don't function. I've swapped out memory, cleared CMOS, unplugged all SATA and IDE devices, etc., but to no avail. Now normally I'd chalk this up to a hardware failure, but the timing and that udev error are highly suspicious to me. As I'm unable to progress at all in the boot sequence, I've not been able to do any additional testing or acquire logs.
I've made some progress -- turns out clearing the CMOS does in fact work, I just wasn't clearing it properly. Still, I cannot boot Fedora as the problem reproduces itself every single time.
You could try: http://www.redhat.com/archives/fedora-test-list/2006-March/msg01542.html which resulted from bug 186164
I moved the file as described in that post with no change in the results. I also notice that prior to the start of nash, I get two possibly related errors: PCI: Cannot allocate resource region 3 of device 0000:00:00.0 PCI: Cannot allocate resource region 3 of device 0000:01:00.0
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. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. 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. Thank you.
(this is a mass-close to kernel bugs in NEEDINFO state) As indicated previously there has been no update on the progress of this bug therefore I am closing it as INSUFFICIENT_DATA. Please re-open if the issue still occurs for you and I will try to assist in its resolution. Thank you for taking the time to report the initial bug.
