Thanks Raimund, that's quite interesting. It is possible that there are two different freeze bugs, and that downgrading libdrm fixed the more severe one but the second one still occurs.
Would you be willing to do a bit more testing to verify if this hypothesis is correct? a. Test with the downgraded libdrm packages installed until the freeze occurs. With the system in the frozen state, ssh into the box and collect the following: * dmesg > dmesg.log * /sys/kernel/debug/dri/0/i915_error_state b. Now upgrade to the stock libdrm where the freeze occurs every time, and reproduce the freeze. With it frozen, collect the same data: * dmesg > dmesg.log * /sys/kernel/debug/dri/0/i915_error_state Attach all four to this bug report. I'll review and compare to see if it is indeed the same bug in both cases, or if actually it's separate bugs. If it is separate bugs as I suspect, I can revert the libdrm patch to at least get that one fixed, and then we can turn focus to the lesser freeze bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753977 Title: [gm45] Xorg freeze - regression starting around Apr 3rd-4th, 2011 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
