good catch, good call. commit 8815ea29a9bcbab2a3c7fbc28987cac67c2c41d0 is a revert for 6d77444aca298b43a88086be446f943cd0442ef7, and is present in the testing branch (i.e., XO-1 802 and earlier), but not in our current 2.6.31 branch. paul =--------------------- paul fox, p...@laptop.org _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
