Summary: no dsdt entry for the A/C adapter causing no entry in
/proc/acpi/* and /sys/class/power_supply
Product: ACPI
Version: 2.5
Kernel Version: current
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Power-Battery
AssignedTo: acpi_power-batt...@kernel-bugs.osdl.org
ReportedBy: justinmatt...@gmail.com
Regression: No
on my iMac9,1 there is no entry in the dsdt for the A/C adapter causing the
kernel to not know what todo i.g. no entry in /proc/acpi/* and
/sys/class/power_supply/* stating the current status. online/offline
on one of my machines there is an error in /var/log/Xorg.0.log:
(II) Apr 29 00:01:04 NVIDIA: Using 768.00 MB of virtual memory for
indirect memory access.
(II) Apr 29 00:01:04 NVIDIA(0): Initialized GPU GART.
(WW) Apr 29 00:01:04 NVIDIA(0): ACPI: AC power state information is
not available under
(WW) Apr 29 00:01:04 NVIDIA(0): /sys/class/power_supply/ , nor under
(WW) Apr 29 00:01:04 NVIDIA(0): /proc/acpi/ac_adapter/
(WW) Apr 29 00:01:04 NVIDIA(0): ACPI: failed to determine the system's
current power source
(II) Apr 29 00:01:04 NVIDIA(0): Setting mode "nvidia-auto-select"
resulting in nvidia defaulting the system being on the battery(even though
iMac's don't have batteries).
regardless of nvidia's status though the entries in /proc/acpi/* and
/sys/class/power_supply remain empty.
attached(when I locat it), is the iMac's dsdt dmesg and Xorg.0.log
