I've mirrored their entire site and tried the files one by one, the offending item is: http://mundoplus.tv/tpl/v3/panBR.png Most likely because it's because this image has a pretty large height (8K pixels).
I've also kept a copy of that file (in case they change they site we can still run the repro: http://pages.minimum.se/crashers/ddx_stressers/panBR.png Further, I've also found that adding: Option "EXANoUploadToScreen" "true" in the device section of xorg.conf makes the bug go away. This means we can rule out the other EXA hooks (less lines of code in the driver to search in) Finally, otaylor over at red hat confirmed this bug on a r500 chipset running Fedora 10 so the range of affected hardware is most likely all radeon r100 up to r500. F10 still dont have radeon-rewrite branch bits so they couldn't record the GPU command buffer contents though. ** Description changed: -ati driver freezes (CPU spinning in X or an ioctl GPU lockup depending on whether compiz is OFF/ON). REPRO STEPS: 1. (using firefox) visit website http://mundoplus.tv/ Note: This bug goes away completely when you set "DRI" "off" or if you - use "AccelMethod" "XAA". + use "AccelMethod" "XAA" or if you set "EXANoUploadToScreen" "true". The + bug also repros on Fedora10. When compiz is ON, this results in a GPU freeze, xorg bt shows it's permanently blocking on ioctl() and it takes 0% CPU. When compiz is OFF, this results in 100% CPU spin in xorg (Note: for dual machines this will show up as 50% CPU or 25% CPU for quad core), in this case repeated xorg bt sampling shows: #1 0xb7d35ea9 in ioctl () from /lib/tls/i686/cmov/libc.so.6 #2 0xb7b30a6d in drmDMA () from /usr/lib/libdrm.so.2 #3 0xb7aa1948 in .....SOME_FUNCTION_HERE... (and basically if you put breakpoints on these three top most stackframes it hits 1 and 2 but not ....SOME_FUNCTION... even though it seems that ....SOME_FUNCTION.... is different from different systems.

This problem happens when I play some games (Supertuxkarts and Planet Penguin Rancer) but not with all (OpenArena works fine), and when I visit some websites like mundoplus.tv (I think that happens in this site because it uses jquery, with flash desactivated it happens too).
