Description of problem: The latest testing kernel kernel-smp-2.6.12-1.1435_FC4 and previous FC4 kernels hang at boot with latest HP firmware for this workstation (version 1.25 Rev a). The last thing on the screen before the hang is "PCI: Multiple domains not supported". Apparently, this is a known issue as described in: http://bugzilla.redhat.com/hwcert/show.cgi?id=155247 and also: http://kbase.redhat.com/faq/FAQ_85_5927.shtm Would it be possible to patch Fedora kernels so that they take pci=noseg and pci=nommconf options, like RHEL4 U2 is going to do take? This would avoid turning off ACPI altogether on this workstation. Version-Release number of selected component (if applicable): 2.6.12-1.1435_FC4 How reproducible: Always. Steps to Reproduce: 1. Boot with ACPI enabled. Actual results: Kernel hangs. Expected results: Should boot with options other than acpi=off.
It really needs fixing upstream, which aparently is queued for 2.6.14 I'll take a look at backporting it sometime.
Mass update to all FC4 bugs: An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks.
Yeah, works great, both with UP and SMP kernels. Thanks!
