This fix is already in 2.6.35, so this doesn't seem to be an issue.

Ryan,
Cant say that this patch (https://lkml.org/lkml/2011/1/6/131) worked for me since I am not able to reproduce the problem quite reliably and now not getting the problem even under the original kernel without this patch. Just wondering what triggers this problem.
