DMESG log shows a diff between normal and abnormal suspend/resume attempts -
I also experience this problem and have noticed that the first suspend/resume which is normal has IRQ Breaking affinity messages but the subsequent failed suspend/resume attempts do not have the IRQ affinity messages either on my machine or on the log this reporter has attached. The messages I am referring to in Chris Wilcox attached dmesg log above are: [ 584.585150] Breaking affinity for irq 12 [ 584.585167] Breaking affinity for irq 20 These messages only appear during the first and only normal suspend/resume after system boot. Subsequent failed suspend/resume attempts do not include the above messages. -- suspend works once then fails on all subsequent attempts https://bugs.launchpad.net/bugs/543562 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
