Dear Maintener, After search with google, i found in bugzilla the exactly same description of the bug, but it seems that it's interest nobody within the kernel mainteners. Bug 60595 in bugzilla[1] Another Search i found in Archlinux Forum[2] Very interesting informations, it's describe the problem but also the last message give me an solution. *blacklisted* *hp_wmi *and all works fine. So now i think the module* hp_wmi* seems caused the problem. Another Search : Found another information with Google a bug of hp-wmi for an user in 3.9 and the patch to correct his problem. i think that may be the actually problem which cames with the 3.9+ kernel is caused by this patch patch hp-wmi[3] Best Regards. Philippe Merlin
