Description Tob Sch 2006-08-07 14:03:57 UTC

I'm using the newest SUSE 10.1 x86_64 kernel 2.6.16.21-0.13-default.

I discovered, that the /proc/acpi/battery/C*/state files are not updated by the kernel. So for example also the "KPowersave" information icon always shows the wrong (old) capacity.

But after doing a "cat /proc/acpi/thermal_zone/TZ1/temperature", the kernel seems to freeze for 2-3 seconds, after that, the kacpid consumes 100%, but the kernel is updating /proc/acpi/battery/C*/state (for a while).
That seems to be a kernel bug :-(

Comment 1 Tob Sch 2006-08-07 14:20:27 UTC

Sometimes the kernel hangs (without any messages).

Sometimes I get following message (without kernel hanging):

Aug  7 16:03:23 MyLaptop [powersave]: WARNING (continueEvent:264) Could not exec
ute program /usr/lib/powersave/scripts for event daemon.scheme.change: No such f
ile or directory

Comment 2 Lars Marowsky-Bree 2006-08-07 15:24:14 UTC

Retrieving the battery state is an ACPI function.

Or BIOS.
Best you search for the newest BIOS of the machine first.
If you still have problems, please attach acpidump and dmesg output.

This is probably a duplicate of:
http://bugzilla.kernel.org/show_bug.cgi?id=5534

We also have such a machine. I try to have a look at it this week.
-> Still better go for the latest BIOS.

Comment 4 Tob Sch 2006-08-08 15:32:53 UTC

The same happens with the newest BIOS (F.OF) from http://h18007.www1.hp.com/support/files/hpcpqnk/us/locate/64_6170.html#0

Holger/Seife:

Any idea how that could happen

The nx6125 has ACPI problems with current kernels, also see:
http://bugzilla.kernel.org/show_bug.cgi?id=5534
I currently try to figure out what is going wrong here, but it's complicated...

Comment 7 Thomas Renninger 2006-08-18 14:10:19 UTC

This is probably a duplicate...
Does boot parameter: ec_intr=0
help here?
