I can confirm that the problem occurs on 2.6.31-22-generic kernel on my Karmic (as I have mentioned earlier in comment #18). I have at times experienced a dozen good resumes before the problem appears again. It does not occur at the same frequency. So even after several successive good resumes, I have experienced the bug in quick succession afterwards.
Currently, the only good config that works for me is 2.6.31-14-generic on Karmic. Installing linux-backports-modules-alsa-2.6.31-14-generic makes the internal microphone work on that kernel. -- Unexpected power-off during boot or when resuming from suspend https://bugs.launchpad.net/bugs/588194 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
