Hello all, I'm not sure if this problem belongs here, I have no other idea where to post however.
My kernel boots up with performance cpufreq governor, thus setting frequency to 2hgz. Then I change it to powersave governor, thus setting frequency to 1ghz just like that: echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Everything works well. Then I launch mplayer and in 1/4 - 1/5 cases system hangs (I mean nothing works, including numlock and sysrq key). I suspect it's something with video card driver, and here comes my problem. I use ati's proprietary fglrx driver (i guess they may be calibrating they own delay loop, or something, and cputfreq change ruins it), so kernel is tainted, so you are unable to track the problem down.... eh.... well, but i hope there is some tiny chance there is something wrong i do, or maybe cpu doesn't like so drastic freq changes... well, if anybody has some idea, or just experience like mine, I ask for help.
