Summary: HAL does not provide battery information on RHEL5 and
CentOS-5
Product: ACPI
Version: 2.5
Kernel Version: 2.6.36
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: Yes
On LWN I was requested to report the following regression.
Due to the cleanup of various /proc/acpi entries from the 2.6.36 kernel
(notable /proc/acpi/info) RHEL5's HAL daemon (Hardware Abstraction Layer) does
not provide ACPI power_management information. Because of this, the Gnome Power
Manager fails to report any battery status, despite the fact that other
applications, using sysfs, do not seem to be affected (KDE, dstat, acpi, ...)
You can verify this using:
lshal | grep battery
or
lshal | grep power_management
or
hal-device-manager
More information about the change that caused this issue is available from:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.36.y.git;a=commitdiff;h=2245ba2a3a975656bb303dfaa115accaa4667083;hp=e2e96c663639a3361bb1a84e666887d308c6c87e
The ELRepo project provides mainline kernels for RHEL5 and CentOS-5 both for
people to test their hardware on recent kernels (so we can backport them), as
well as using these kernels for reporting regressions upstream.
