That's right. I had idea that maybe we lack some ACPI initialization on resume, decided to check it. I used my workaround to do not restore backlight on resume and after successful resuming I tried: # echo 5 > /sys/class/backlight/acpi_video0/brightness It worked fine. So this lock up happens when we change brightness while whole resume only. If we change brightness before suspending or after resume is done, it works fine. I suspect that maybe there is some other driver doing it's resume which affects us. Maybe it does something just before or just after video.c resume? Maybe we don't have enough delay between out resume and other driver resume? Can this be the case? -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
