Comment 2 for bug 457523

Hi,

The warning reported in the attached OopsText.txt log appears to have been resolved with a patch from upstream (I'll past the commit message below). This patch is now in the next 2.6.31.6 upstream stable kernel patch set which will soon be applied to the Ubuntu Karmic kernel as a Stable Relesae Update. In the mean time, I've built the following test kernel to verify this patch does indeed resolve this issue. If you could test and provide feedback that would be great. Thanks!
