From title: running latest update-kernel Sorry, I should have spotted this immediately: Does that mean this is a regression from 12.1 kernel version update? If you still remember or can look up the previous working kernel version, that would help a lot. If this is the case I should have a good chance to find the offending patch by grepping through the (not that huge) diff of latest stable kernel update
