--- Comment #7 from Peter <lekenst...@gmail.com> 2012-05-16 12:07:45 --- Rafael, the nvidia card can be disabled through the _PS3 method and is done with `pci_set_power_state(dis_dev, PCI_D3hot);` as you can see on https://github.com/Bumblebee-Project/bbswitch/blob/d12ce73a0d042fce3738aea800f55f8a23874e8c/bbswitch.c#L240 switcheroo does something similar. I think I have found the real issue. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=drivers/acpi/scan.c;h=7417267e88fa9763617e0cc7e36fde6154ff4335;hb=1cc0c998fdf2cb665d625fb565a0d6db5c81c639#l906 905 /* Set defaults for D0 and D3 states (always valid) */ 906 device->power.states[ACPI_STATE_D0].flags.valid = 1; 907 device->power.states[ACPI_STATE_D0].power = 100; 908 device->power.states[ACPI_STATE_D3].flags.valid = 1; 909 device->power.states[ACPI_STATE_D3].power = 0; With the change, ACPI_STATE_D3 has become "4": include/acpi/actypes.h:502:#define ACPI_STATE_D3_HOT (u8) 3 include/acpi/actypes.h:503:#define ACPI_STATE_D3 (u8) 4 include/acpi/actypes.h:504:#define ACPI_STATE_D3_COLD ACPI_STATE_D3 @rocko, can you revert the patches and try ACPI_STATE_D3_HOT instead of ACPI_STATE_D3 for those lines? -- 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.
