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 2. 3. Actual results: Hangs at ACPI Expected results: Normal boot Additional info:
Please try: pci=nomsi also: pci=nomsi,nommconf
pci=nomsi makes no difference pci=nomsi,nommconf works
This problem exists in F 8 test3.
I have upgraded to kernel 2.6.23.1-23.fc8, and the problem persists.
try pci=noacpi ?
Kernel 2.6.13.1-31.fc8 x86_64: pci=nomsi: No go, stops at ACPI pci=nomsi,nommconf: OK, works pci=noacpi: Kernel panic
Should have been: kernel 2.6.23.1-31.fc8 x86_64 The call trace from the panic with pci=noacpi is: <IRQ> handle_level_irq+0x3c/0xe4 do_IRQ+0xf1/0x161 ret_from_intr+0x0/0xa <EOI>__delay+0x8/0x10 timer_irq_works+0x20/0x3e setup_IO_APIC+0x5d6/0x88d I'll try to find a camera to get a screenshot if more information is needed.
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 concerns.
can you attach your dmidecode output ? We should be able to add a quirk to work around this.
Created attachment 240231 [details] dmidecode from a dc7700
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.
