Ok great, the testing done so far appears to be pinpointing this to an issue fixed with newer kernel drm code. It's possible a specific patch resulted in the fix. In that case, the next logical step is to do a git bisection search on the kernel code to locate the fix. The procedure is a little technical but is well documented at https://wiki.ubuntu.com/Kernel/KernelBisection. I'll reassign to the kernel meanwhile.
Btw, drm code can be a bit thorny, and even if the solution is narrowed to a specific git commit, extracting and backporting it might be pretty tricky. But the kernel team can follow up with advice on the issue; please contact them if you have additional questions. ** Package changed: xserver-xorg-video-intel (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/599017 Title: [gm45] Xorg freeze on Firefox on one particular page _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
