But agpmode=4 has > works with the older kernels, so I don't think that is the issue So I've tested with radeon.agpmode=-1 yesterday and today. I've performed three tests, and each time the freeze happened. The first time the freeze happened soon after booting, while starting firefox (although I was also running the 'antspotlight' screensaver in a window. The other two times the freeze took a bit longer to manifest (45minutes to an hour). The third freeze occured while rebuilding my kernel to re-include the 'vram at zero' patch. So the freezing issue exists even in PCI mode. Tested with kernel 26bf62e47261142d528a6109fdd671a2e280b4ea - Merge branch 'drm-radeon-next' of ../drm-radeon-next into drm-core-next , with additional patch to print vram and gtt locations. dmesg | grep -iE 'radeon|agp' contains the following (lines starting with 'RADEON:' mine): ---8<--------- ... gpgart-intel 0000:00:00.0: Intel 855PM Chipset agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000 [drm] radeon defaulting to kernel modesetting.

Can anyone please confirm these results? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
