Linux for 939A8X-M AMD Athlon 3200+ -apm,acpi,noapic problem

I am using mandriva 2008 One for now. I added apm=power-off , acpi=off and noapic in boot. These prevented the system from hanging after a few minutes running. However some things do not work correctly, one of which is the screensaver. It just goes into power off monitor instead and no screensaver comes up. Ubuntu used to hang the same way without those commands, but when i added them it didn't shutdown completely. Therefore i cannot use it. I have a multiple boot right now and have WinXP , ubuntu and mandriva. i wish to switch to ubuntu but even the latest release gave me the same problem. IS THERE A LINUX DISTRO WHICH IS NOT AFFECTED BY THIS BUG? i am using 939a8x-m motherboard with AMD athlon 3200+. onboard sound and ethernet and ATI radeon 9600XT. I never installed older kernels but while i used some old versions as livecd, none gave me these problems. Do i need to stick to old versions to remove this problem? thanks

try this as superuser (su) [b]lsmod |grep apm[/b] if nothing shows up do [b]modprobe apm[/b] on boot line also add [b]apm=on[/b] just before [b]apm=power-off[/b] might also try adding this line [b]apm power_off=1[/b] to /etc/modules [Modified by: Stef on July 16, 2008 01:00 PM]
