dac922, thanks a lot for your analysis. I've uploaded a test kernel here: http://people.canonical.com/~henrix/lp1215513/
(there are 2 directories, one for 32bits and another for 64bits) Could the original bug reporter please also test it and report back? This is a Raring kernel reverting commit referred in comment #11 (upstream commit 57ab048 "zram: use zram->lock to protect zram_free_page() in swap free notify path"). This commit actually introduces a regression that is fixed upstream but its backport to Raring seems to require a few additional commits. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1215513 Title: System locks up, requires hard reset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1215513/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
