Problems with Kernel 2.6.13.2 and Acer Travelmate 4002lmi
Hallo everybody, I have a problem with kernel 2.6.13.2 and my notebook Acer Travelmate 4002lmi(SBS battery). I have used Suse 9.3 with Kernel 2.6.8 and a patched DSDT from the https://sourceforge.net/projects/sbs-linux/ package. All work fine. Now I have install Opensuse 10.0 RC1 with Kernel 2.6.13 and when I am activate ACPI the kernel needs 20 seconds to boot and the following Warning appears in the boot log and in the kernel log: <6>ACPI: Embedded Controller [EC0] (gpe 29) <4> ACPI-1048: *** Warning: Failed to acquire semaphore[dfec5960|1|0], AE_TIME (More see attachment) And my battery applet in KDE shows no battery status(powersave, kpowersave). But when I use acpi -b in the terminal the right battery level were displayed. I have updated the Kernel with apt to 2.6.13.2 and the powersave package. What means this warning/failure? What is the problem? (solution). When I disable acpi the kernel boots normally. Thanks for any help Simon Laschka
Inspecting /boot/System.map-2.6.13.2-20050926142533-default Symbols match kernel version 2.6.13.

Please test 2.6.14-rc1 or later, boot kernel with ec_burst=1.
