Yes and no change. I even tried to disable wireless in BIOS boot and then enable it again. No change... It seems somebody already had the same problem https://bugzilla.redhat.com/show_bug.cgi?id=639184. My BIOS doesn't provide any locator setting, unfortunatelly. The message above says that the HW is still in a deep sleep state. Can we somehow force waking it up? Or, can we just ignore the signature check and (maybe) fix it by another suspend/resume cycle? -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.
