Sounds like this problem introduced in the RC7? https://lkml.org/lkml/2012/7/15/104
And fixed upstream in: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blobdiff;f=kernel/time/timekeeping.c;h=3447cfaf11e7d61b11d30bc063967e47d85e59d4;hp=269b1fe5f2ae2f7e6c0bb0fac8ce9a54e2d4d278;hb=3e997130bd2e8c6f5aaa49d6e3161d4d29b43ab0;hpb=33d519feaccb8a1208f736d00f53a2a73d98ffaa 3.5.0-5.5 (the RC7 rebase) hits this bug for me. While up to and including 3.5.0-4.4 is unaffected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027182 Title: Dell Lat D420 cannot come out of suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1027182/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
