Display, mouse, keyboard freezes when desktop repainted

[daytooner]

In short, as the title says, the display, mouse, and keyboard freeze whenever a part of the desktop gets repainted. I think, but not sure, it happens when any part of an existing window gets covered by a part of another window. Updates within a window are okay. But if a dialog, or even a tootip pops up, everything hangs for many seconds. I can drag a window, but if it touches another window, then the same.


I have a radeon card, running R300 code. I have this in dmesg:


[drm] Initialized drm 1.1.0 20060810
radeon 0000:01:00.0: can't find IRQ for PCI INT A; probably buggy MP table
[drm] Forcing AGP to PCI mode


I am running F11.

FWIW: this is on an old(er) PC: dual PII 400MHz. Granted it is slow, but I also had an nvidia card in it before, and never had this problem (on F9 and F10). So I am (only) guessing that the F11 radeon driver is doing this.

Are there any options to the radeon module that might help? My BIOS has a bunch of AGP options. Anything in particular that might affect this?

TIA

I hope you get a reply soon.

I'd be interested in any responses.

I'd be interested in anything myself. But haven't heard from anybody.

I did read somewhere that this was a known bug with the radeon driver. But I still haven't found any solution.

Interestingly, on another F11 system with an NVidia board, a similar thing happened: mouse jerky, keyboard slow to react, etc. It happened when a rogue application took over the CPU (100% in use). When I killed the app, everything was back to normal. So maybe the radeon display is hogging the CPU somehow?

Just a guess, since no one else seems to know.
