Don't know if this is helpful or not but: I have Thinkpad T40 with Radeon Mobility M7 LW [Radeon Mobility 7500]. I've not seen any rogue CPU usage, but I HAVE seen screen corruption at the top of the screen. Just searching for any dupes of this behaviour and this bug is the closest I've seen. The corruption is limited to the top menubar under Gnome (not tried KDE) and extends in from the left to roughly half way across the "Places" menu title. Corruption disappears when you select those menus and they get redrawn. As luck would have it, the corruption isn't there right now, but I'll post a screenshot as soon as I can.

Screenshot of screen corruption at top left of screen
Corruption disappears when the menus are selected. Corruption also changes
slightly after period of time - not sure how long, but I can now read the
Applications and Places menu titles clearly although they still have a red
streak behind them and the 'f' icon background is a bit garbled.
Am running Xen hypervisor kernel BTW if this makes a difference - uninstalling now to see if corruption still evident under normal kernel. Haven't seen any corruption since the re-install without the Xen hypervisor. Is this a Xen issue? It's good to know if Xen is influencing the problem at all or not. From there though, it could be a Xen kernel bug, or an X bug, or something else perhaps. Update to the latest Fedora development packages, including the kernel, and then while booted in the kernel that reproduces the problem, please attach your X server log and config file from that invocation for further diagnosis. Try disabling DRI, and also try disabling 2D acceleration with Option "noaccel" also if the problem is still present in the current rawhide kernels. TIA I can confirm that the problem persists when running the latest kernel (1.1996) with the latest updates, when DRI is enabled. No such problems when DRI is disabled.

X server log when problem occurs
Created attachment 125501 [details]
X config file
This is the current version, with DRI disabled. The problem occurs when DRI is
enabled.
Seems to be a bug in the radeon kernel module on R300 hardware, which occurs when the kernel module is loaded, even if userland does not have r300 DRI support. *** This bug has been marked as a duplicate of 182196 *** |
