Hey all, Since moving a 4.3 x86-64 install from a single athlon64 to a new dual core AMD cpu it would appear that cool'n quiet is having trouble as is shown in the system logs; powernow-k8: ignoring illegal change in lo freq table-2 to 0x2 powernow-k8: transition frequency failed Any ideas ? Cheers, Brian.

I disable it on all my systems and haven't had any issues as a result. Cheers,
I thought Powernow would not be running at all on default CentOS 4 since AMD says to recompile the kernel with the linux driver package they provide, and the latest drivers don't work with kernels before 2.6.9, anyway. After your three postings I googled around and found I have to load the powernow and cpufreq-ondemand modules. I did so on one of my machines and changed the governor to ondemand. Seems to work so far, no error messages yet. My machines are on AM2 sockets. One problem I have is that I don't get cpuinfo_cur_freq, only scaling_cur_freq. I also don't get any temperatur reading via /proc/acpi/thermal_zone, but I assume that's because of the chipset? (nforce 430).

I got two a few days ago and both have the same problems in gnome (I didn't try another window manager). 1. they randomly repeat characters I type. It's not that they repeat too fast or too early or so. It just happens randomly but much too often. I had to disable the key repeat. I tried the nvidia supplied X server/display driver but this didn't make a difference. I remembered that the CentOS Live CD doesn't have this problem and when I booted into it again and checked the kernel it was clear why: it uses the normal kernel. 2. the menus of the upper action bar often don't stick. Very often they go away right after the click, so that I have to press the mouse key most of the time to keep them in sight. I haven't noticed any other bad signs for non-X programs and if it is confined to X or gnome only I'm happy, but I fear there might be more serious problems only revealed over time.
