I will unmark this as a duplicate of bug 464552, here are the differences between my problem and the problem reported there:
1) Coming out of suspend works just fine (and pretty fast). It's going into suspend that takes an unusual long time: Ubuntu goes to a blank screen but then an empty console appears (cursor blinking) and stays there for ~20-30 seconds before it goes to suspend. As a comparison, Windows 7 goes to suspend (well, "sleep") in at most half the time it takes Ubuntu to do so on the same machine. 2) When coming out of suspend, the screen is dimmed, even if the laptop was plugged the whole time, which would indicate some sort of actual error, not just a false timeout. If there's any other info I could provide I'd be more than happy to. ** This bug is no longer a duplicate of bug 464552 suspend_test_finish warning triggers too easily, increase timeout to match mainline times -- WARNING: at /build/buildd/linux-2.6.31/kernel/power/suspend_test.c:52 suspend_test_finish+0x80/0x90() https://bugs.launchpad.net/bugs/467657 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
