[mmconf] Kernel freeze during PCI bus probing on DG33TL Intel MotherBoard
Last modified: 2007-11-30 17:12:16 EST
Description of problem:
See "Summary" of the bug.
Version-Release number of selected component (if applicable):
kernel-18.104.22.168-76.fc7 or kernel-2.6.21-1.3194.fc7
Steps to Reproduce:
1. Having the hardware (see http://www.intel.com/products/motherboard/DG33TL/
for more information) with latest BIOS version installed
2. Boot from USB stick w/o kernel parameters the liveCD of F7 i386 or x86_64
See the freeze happening.
I must boot with pci=nommconf kernel parameters to finish install from USB stick
(F7 i386 and x86_64).
I'm having other troubles with kernel on this hardware, other bugs will follow
regarding support for this MotherBoard. Not enough time ...

FYI, the USB stick installation method was chosen because of an other freeze due
to pata_it821x module (DVD install method from PATA on board chipset). An other
bug report will follow.

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.
This bug has been marked as possibly resolved in 2.6.23 - could you do so when
it becomes available (or even install a 2.6.23 rawhide kernel if you are able
to) and advise whether it works for you.
I can confirm that 2.6.23*-git-* vanilla kernel do not work better regarding PCI
bus probing with mmconfig (almost same .config that's the one shipped is F7
Haven't tested Fedora rawhide kernel ...
The developers will need you to test with a fedora kernel as opposed to vanilla.
The config may be *close* but the patches include are numerous and it is what
they work from. If you can test with a fedora kernel therefore that would be great.
I'm closing this bug because mmconfig has been disabled in Fedora 8 kernel.
