Ubuntu desktop occasionally got frozen.

Sun Apr 1 05:01:36 UTC 2012

Hi KK,
I reported the bug here: https://bugs.launchpad.net/bugs/965914
I think there are no similarities between your situation and mine.

I installed the mainline kernel 3.3.0-030300-generic for 4 days.
Since I installed the new kernel, my notepad works normally and no freeze
happens again. I'll continue to  test the new kernel for several days to
see whether the bug is actually fixed.

Thanks and good luck.

Best regards.
