Description Mogens Kjaer 2007-08-09 13:20:20 UTC
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):

How reproducible:

Steps to Reproduce:
1. Boot installation on HP DC7700
Actual results:

Comment 2 Mogens Kjaer 2007-08-10 06:48:31 UTC
pci=nomsi makes no difference
pci=nomsi,nommconf works

Comment 3 John Summerfield 2007-10-21 22:43:50 UTC
This problem exists in F 8 test3.

Comment 4 John Summerfield 2007-10-22 00:06:52 UTC
I have upgraded to kernel, and the problem persists.

Comment 5 Dave Jones 2007-10-25 04:59:47 UTC
try pci=noacpi ?

Comment 6 Mogens Kjaer 2007-10-25 06:28:34 UTC
Kernel x86_64:

pci=nomsi:            No go, stops at ACPI
pci=nomsi,nommconf:   OK, works
pci=noacpi:           Kernel panic

Comment 7 Mogens Kjaer 2007-10-25 06:52:18 UTC
Should have been: kernel x86_64

The call trace from the panic with pci=noacpi is:

<IRQ> handle_level_irq+0x3c/0xe4

I'll try to find a camera to get a screenshot if more information is

Comment 8 Jesse Barnes 2007-10-26 23:39:49 UTC
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 

Comment 9 Dave Jones 2007-10-27 00:21:36 UTC
can you attach your dmidecode output ?  We should be able to add a quirk to work
around this.

Comment 11 Will Woods 2007-10-31 20:27:34 UTC
Could you try booting the boot.iso from today's rawhide? We've turned off PCI
MMCONFIG, which should fix the boot hang here.

Comment 12 Mogens Kjaer 2007-11-01 07:22:12 UTC
Yes! It works.

I can boot the installation from the boot.iso image.
After the installation the machine boots without any extra boot options.

Comment 13 Brian Maly 2008-04-09 18:20:25 UTC
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.
