reverted(It is commit 47f80be7 in the Ubuntu source tree). The test kernel can be downloaded from: http://people.canonical.com/~jsalisbury/lp1064924 It would be helpful if folks affected by the regression in Ubuntu can test that kernel and confirm it fixes the regression? Please be sure to install both the linux-image and linux-image-extra .deb packages. Thanks, Joe
