Did this issue start happening after an update/upgrade? Were you running any Precise kernels prior to linux-image-3.2.0-17?

[Joseph Salisbury (jsalisbury)]

There is a test kernel available for this bug at:
  http://people.canonical.com/~apw/lp922906-precise/

Can you test this kernel and report back in bug 922906 where or not the test kernel resolved this bug?
