Description of problem:
Booting installation on f8test1 x86_64 on an HP DC7700 hangs at:
ACPI: Interpreter enabled
ACPI: (supports S0 S3)
ACPI: Using IOAPIC for interrupt routing
ACPI: PCI Root Bridge [PCI0] (0000:00)
Fedora < 7 all had the same problem. The problem was solved in
all kernels of F7, now it comes back in F8test1.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot installation on HP DC7700
Hangs at ACPI
pci=nomsi makes no difference
This problem exists in F 8 test3.
I have upgraded to kernel 188.8.131.52-23.fc8, and the problem persists.
try pci=noacpi ?
Kernel 184.108.40.206-31.fc8 x86_64:
pci=nomsi: No go, stops at ACPI
pci=nomsi,nommconf: OK, works
pci=noacpi: Kernel panic
Should have been: kernel 220.127.116.11-31.fc8 x86_64
The call trace from the panic with pci=noacpi is:
I'll try to find a camera to get a screenshot if more information is
There was a patch in -mm called
pci-disable-decode-of-io-memory-during-bar-sizing.patch that may fix this
hang. At the moment, Greg is reluctant to push it upstream over Ivan's
can you attach your dmidecode output ? We should be able to add a quirk to work

Could you try booting the boot.iso from today's rawhide? We've turned off PCI
MMCONFIG, which should fix the boot hang here.
Yes! It works.
I can boot the installation from the boot.iso image.
After the installation the machine boots without any extra boot options.
Was pci-disable-decode-of-io-memory-during-bar-sizing.patch the patch that
resolve this issue? I.e. this was the patch that went into the boot.iso kernel?
I ask in reference to BZ 441615 (same bug but for RHEL5) so that I might
identify which patch should be backported to RHEL5.
