As reported in LP bug 371279, many jaunty -ati users are running into GPU lockups or xorg CPU spins when they visit the website: http://mundoplus.tv/ I also suspect that several of the more absurd "performance bugs" (absurd as in xorg constantly taking 50% CPU or so) could be duplicates of this bug because if compiz is OFF and thus the bug becomes a CPU spin that spin will be be limited to a single core and on a modern computer clogging one core out of 4 might make it feel like a perf issue even if your xorg is spinning 100% and the GPU has stopped talking to xorg. Anyway, I'd like to ask you three questions about this issue: A)) any ideas on how I can save this repro? basically, right now if someone running the mundoplus.tv website updates it the repro might not work anymore. I've tried to mirror the site using "wget -m" and such but I can't get it to repro off the mirror. B)) does anyone have any more recent ATI hardware? I've created a list of the affected hardware in the bug report but so far it's a lot of old r300 cards and I'm really curious to see if it affects other ATI series (r400,r500). Even though r600/r700 can't use compiz they might still be vulnerable to the CPU spin variant of this bug. C)) which package should I be bisecting (I have an ATI machine here which consistently hangs when opening mundoplus.tv). I know that the bug disappears if I use "DRI" "off" so I'm wondering if that's sufficient to conclude that the bug is hiding in libgl1-mesa-dri/glx ?? FWIW, it _does_ repro with EXA+renderaccel="off" and it does _not_ repro in XAA. --- Here is the bug numbers for reference (including potential dups): The main MUNDOPLUS.TV bug: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/371279 ATI freeze bugs: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/351990 https://bugs.launchpad.net/ubuntu/+bug/350766 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/350933 https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/368200 POTENTIAL MUNDO DUPS: akkana --> https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/347078 marek szuba --> https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/373434 bjorn --> https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/372528 3ntix --> https://bugs.launchpad.net/ubuntu/+bug/368461 ATI CPU 25% PERF BUG (POSSIBLE MUNDOPLUS DUPS) https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/363238 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/347078 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/365886 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/366299 CONFIRMED NON-MUNDO ATI LOCKUPS: manuel carro --> https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/374780 -- Ubuntu-x mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-x
