When incrementing/decrementing brightness, the brightness levels are randomized (even though I am using the brightness level sort patch from bug 12037). Setting a brightness level directly via sysfs or procfs has either no effect or the wrong effect. Information in /proc/acpi/video/VGA/LCDD/brightness does not correspond to reality. dmesg is full of [ 662.924221] ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.PCI0.VGA_.LCDD._BCM] (Node ffff88013fa303e0), AE_AML_BUFFER_LIMIT [ 663.303518] ACPI Exception (exoparg2-0444): AE_AML_BUFFER_LIMIT, Index (0000000FE) is beyond end of object [20080926] [ 663.303538] ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.PCI0.SBRG.EC0_.STBR] (Node ffff88013fa35e40), AE_AML_BUFFER_LIMIT [ 663.303674] ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.PCI0.VGA_.LCDD._BCM] (Node ffff88013fa303e0), AE_AML_BUFFER_LIMIT [ 663.309624] ACPI Exception (exoparg2-0444): AE_AML_BUFFER_LIMIT, Index (0000000FE) is beyond end of object [20080926] [ 663.309644] ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.PCI0.SBRG.EC0_.STBR] (Node ffff88013fa35e40), AE_AML_BUFFER_LIMIT [ 663.309781] ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.PCI0.VGA_.LCDD._BCM] (Node ffff88013fa303e0), AE_AML_BUFFER_LIMIT [ 812.406381] ACPI Exception (exoparg2-0444): AE_AML_BUFFER_LIMIT, Index (0000000FE) is beyond end of object [20080926] [ 812.406401] ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.PCI0.SBRG.EC0_.STBR] (Node ffff88013fa35e40), AE_AML_BUFFER_LIMIT [ 812.406537] ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.PCI0.VGA_.LCDD._BCM] (Node ffff88013fa303e0), AE_AML_BUFFER_LIMIT -- 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, or are watching someone who is. ------------------------------------------------------------------------------ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
