Bug 189911

I should have added that the code that changed is in arch/i386/pci/mmconfig.c.
I'm not sure why this is a "BIOS Bug" now where it seemed to work before 
but if there's an error path that's supposed to work, it doesn't.

Hmm, I turned on MSI in the rawhide kernel a little while ago, I wonder if
that's the cause.

I've enabled it in the work-in-progress errata for FC5 which you can get at
http://people.redhat.com/davej/kernels/Fedora/FC5/RPMS.kernel/
can you see if that fails in the same way?

I booted the .2101_FC5 i686 kernel on my machine and it booted just fine.

The earliest kernel that I know for sure fails is the rawhide .2127 kernel
so if you have something else between .2101 and .2127 you'd like me to try,
let me know.

Thanks.

is this still causing problems in the 2.6.17 based kernels ?

Yes, the problem is still there.  I just tested with a kernel that Steve 
Grubb builds for the LSPP project, which he just updated to 2.6.17, and
it behaves the same way.

I did try updating the firmware on this system but it didn't help.

Please let me know if there's more I can do.

I should probably mention that a co-worker who has the same model system,
bought at the same time as mine, is also experiencing the problem so its
not just a single machine.  We have one example of an older version of the
same model that doesn't experience the problem.  I'm not sure what the
differnces between the older and newer ones are since they have the
same model number.

This may or may not be related but I've been seeing the same symptoms on a
Toshiba Satellite A40 laptop. This laptop has worked with every kernel since FC2
but the last FC5 update it worked on was kernel-2.6.16-1.2133_FC5. All 3 (?)
subsequent updates fail to boot with the final few lines of output being as
follows: (written down and typed in so may have typos)

ACPI: PCI Interrupt Link [LNKA] (IRQs *10)
APCI: PCI Interrupt Link [LNKB] (IRQs 3 4 5 6 7 *11)
APCI: PCI Interrupt Link [LNKC] (IRQs 3 4 5 6 7 *11)
APCI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 6 7 *11)
APCI: PCI Interrupt Link [LNKE] (IRQs 3 4 5 6 7 *11)
APCI: PCI Interrupt Link [LNKF] (IRQs 3 4 5 6 7 *11)
APCI: PCI Interrupt Link [LNKG] (IRQs 3 4 5 6 7 *11)
APCI: PCI Interrupt Link [LNKH] (IRQs 3 4 5 6 7 *11)
ACPI: PCI Root Bridge [PCI0] (0000:00)
ACPI: Assume root bridge [\_SB_.PCI0] bus is 0
[...hangs here...]

Now, I tried a few kernel options to try to get to the bottom of it and here
were the results:

acpi=off makes it hang on "PCI: Probing For Hardware" instead

acpi=off pci=off makes it boot OK, but only works in text mode

pci=nomsi doesn't help at all.

pci=nobios WORKS fine, superficially. I'm entering this bug report now running
from kernel-2.6.17-1.2157_FC5.

Does this help?

Further to comment #8, here's the lspci output on my Satellite A40

I just tried the latest rawhide kernel (2.6.17-1.2548.fc6)
and my x86 box now boots.  It looks like there are alot more
boot messages now.  Is there anything of interest that you'd
like from my system?

I'm very happy that it boots now. :-)

If it boots, I guess we're done :)

Yep, the latest FC5 updates kernel (2.6.17-1.2174_FC5) solves this problem for
me too.
