--- Comment #22 from Peter <lekenst...@gmail.com> 2012-05-17 20:59:34 --- I added a bit more debugging, the "transitioning from D..." message comes right before the if condition "state < device->power.state", acpi.debug_layer=0x550000: [ 16.968478] ACPI: transitioning from D255 to D4 [ 16.968485] ACPI: Executed _PS4 for device [PEGP], status: 5 [ 16.968487] ACPI: Device [PEGP] failed to transition to D4 [ 17.007702] utils-0286 [00] evaluate_integer : Return value [0] [ 17.123579] utils-0286 [00] evaluate_integer : Return value [1] [ 17.175566] utils-0286 [00] evaluate_integer : Return value [28] The same message occurs after resume. It seems that initially the power state is (unsigned char)-1 and therefore it thinks that it's greater than the target state D3. Since machines with _PR3 are uncommon (I haven't seen one so far), this issue could be hidden for a long time (without power resources, the end result is the same). Again, I'm happy to test any patches :) -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
