Comment 8 for bug 112120

I'm experiencing the same problem, as well as bug 91545. I tried your patch above, but it hasn't worked, guidance-power-manager is still crashing, as well as the display configurator.
Should I mess with the settings in the BIOS regarding ACPI? I tried setting the CPU scaling to performance, but according to powernowd, CPU scaling is "not supported"; I don't know if that's a harware issue or a software issue, since this is a Pentium D 3.0Ghz with the following kernel:

$ uname -a
Linux freerick-desktop 2.6.20-15-generic #2 SMP Sun Apr 15 06:17:24 UTC 2007 x86_64 GNU/Linux

The output of the lshal command is also attached to this post, so you can review it. Since I'm using an x64 platform, I can't use the updated packages that you have released. Do you maybe have a tarball I can compile? Any help with this would be much appreciated.

In addition, my ethernet adapter dies every once in a while, usually after a period of inactivity. From what other users have posted, this appears to be a power management issue; the kernel logs the following:

May 15 06:51:14 freerick-desktop kernel: [ 4409.351884] NETDEV WATCHDOG: eth0: transmit timed out
