Oh, the "machinecheck" rule triggers it, get it now. But, because the power state is not changed, LMT doesn't reload. I have to change RUN to "lmt-udev auto force" to make the apm level setting works again after resume. (it has a side effect, which takes much longer time during suspend and resume.) Anyway, thanks for your help, will try to fix it in kernel space. -- Adam Lee http://adam8157.info -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
