Created attachment 517597 [details] Dmesg Description of problem: [ 0.445252] pci_root PNP0A08:00: address space collision: host bridge window [mem 0x000cc000-0x000cffff] conflicts with Video ROM [mem 0x000c0000-0x000cedff Do see display glitches ( fonts weird not all icons showing unless I move the mouse pointer to the missing side then they appear etc.. ) but that could be Gnome-shell or the Xorg driver. The card is. 01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility Radeon HD 4200] Version-Release number of selected component (if applicable): 3.0.1-3.fc16.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Did this just start happening with a recent kernel or has it been happening on older releases too?
You can just ignore that message; it's not telling us anything useful. Upstream commit 43d786ed4df4c54cb8802a523748a7d78130a2cb should resolve this (it only downgrades the message from KERN_ERR to KERN_INFO). I'm pretty sure the display glitches are unrelated to this message. You could boot with "pci=nocrs", which will turn off the code that pays attention to the host bridge windows, and should make the message go away. I don't think "pci=nocrs" will make any difference as far as the glitches. If it *does* make a difference, then they're related and we need to investigate more.

From the test list others are seeing clitches hence this seems to be radeon/clutter/gnome-shell not the kernel that causes that.
This keeps getting reported, so I've included the patch from 3.1 to reduce the severity of the warning.
