Created attachment 358216 [details] 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): kernel-2.6.30.5-28.rc2.fc11 How reproducible: Every time Steps to Reproduce: 1. Boot kernel-2.6.30.5-28.rc2.fc11 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
Created attachment 358217 [details] lspci output showing no graphics card detected with this kernel
Created attachment 358218 [details] 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: 1a2 > 00:01.0 PCI bridge: Intel Corporation Mobile 915GM/PM Express PCI Express Root Port (rev 04) 14a16 > 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X700 (PCIE)
Same symptoms with kernel-2.6.30.5-32.fc11. A couple more details about the computer in question: it's an Acer TravelMate 8100 with a Radeon X700 mobility graphics card.

Can you post the contents of /var/log/dmesg after booting each of the working and broken kernels? (separate attachments, plain text)

Can you try adding: pci=noacpi to the kernel boot options?
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...
Created attachment 359048 [details] 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?
Created attachment 359241 [details] output of acpidump Here's the output of acpidump as requested.
Do you still have this issue with new kernel (you can try fedora 12 live cd for instance).
