Comment 48 for bug 1419355

Ok, I will open a new bug report as soon as I've got a little more time on my hands. I still think it's related with this issue though, because without the quirk i.e. with older kernels or witch the patch from comment 16 I get somewhat 50% correct shutdowns while with the HP quirk, that is newer kernels without the patch I consistently get 100% reboots.
