it's a simple reproduction of this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/329645 i've got the same problem either on lenny/squeeze/sid and all possible kernels up to 2.6.34 (not tested yet). can someone tell mi how to send a bug report in that case? launchpad service seems little easier since it doesn't reqiure exact package ;) thanks in advance and all the best t.
