Description Bojan Smojver 2005-08-25 19:42:09 EDT
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:


and also:


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):

How reproducible:

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.
Comment 2 Dave Jones 2005-09-30 02:29:07 EDT
Mass update to all FC4 bugs:

An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel ( 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.

Yeah, works great, both with UP and SMP kernels. Thanks!
