UPDATE: I digged a little further. Looks that on older Android versions the 'Kernel Tick Clock' was set to 100Hz. I would really love to test a kernel with these 'old' settings. There is a long discussion here about that change. I would like to quote some posts of the discussion... 2nd UPDATE We are definitely running with 300Hz with the mautz kernels! You can check that in the kernel config file in /proc/config.gz. Search for 'CONFIG_HZ'! @mautz: So I guess it's worth a try to switch back to 100Hz.
