Xorg.0.log showing the crash

Description of problem:
With the latest kernel, a Radeon X700 graphics card is not detected any more on boot, and X therefore (of course) won't start. The graphics card doesn't even show up in lspci output. Booting previous kernels works fine, so this is clearly a kernel issue.

Version-Release number of selected component (if applicable):

How reproducible:
Every time

Steps to Reproduce:
1. Boot kernel-
Actual results:
X crashes because there is no graphics card

Expected results:
Things working

Additional info:
I'll attach the Xorg.0.log, along with lspci output from a working and a non-working kernel

lspci output from a previous (working) kernel, for comparison

Here's the "diff" between the two lspci outputs -- both of these devices are detected with the working (older) kernel and not with the newer kernel:

> 00:01.0 PCI bridge: Intel Corporation Mobile 915GM/PM Express PCI Express Root Port (rev 04)
> 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X700 (PCIE)

Comment 3 Mary Ellen Foster 2009-08-22 10:51:15 UTC
Same symptoms with kernel-

A couple more details about the computer in question: it's an Acer TravelMate 8100 with a Radeon X700 mobility graphics card.

Possibly related to http://bugzilla.kernel.org/show_bug.cgi?id=13720 ?

Comment 5 Chuck Ebbert 2009-08-26 16:16:51 UTC
Can you post the contents of /var/log/dmesg after booting each of the working and broken kernels? (separate attachments, plain text)

dmesg from broken kernel

Comment 8 Chuck Ebbert 2009-08-27 23:39:02 UTC
Can you try adding:


to the kernel boot options?

Comment 9 Chuck Ebbert 2009-08-27 23:59:27 UTC
Maybe ACPI thinks the video card is in a dock. You can see the IRQ for the bridge get disabled before an undock occurs:

pcieport-driver 0000:00:01.0: PCI INT A disabled
ACPI: \_SB_.PCI0.DOCK - undocking

2.6.29 shows an undock but no IRQ disable...

dmesg when booting with pci=noacpi

Booting with pci-noacpi seems to have worked properly. Here's the dmesg from a successful boot.

Can you install the pmtools package, run acpidump as root and attach the output?

output of acpidump

Here's the output of acpidump as requested.

Comment 13 Jérôme Glisse 2009-10-14 10:58:24 UTC
Do you still have this issue with new kernel (you can try fedora 12 live cd for instance).

Comment 14 Vedran Miletić 2009-12-05 10:34:00 UTC
Reporter doesn't reply for over a month. Closing as insufficent data.
