Way too much bus master activity. I want to find out what is causing it. Any hints how to do that ? I found one possible cause for some of the activity. Without X i have a 50:50 mix between C2 and C3. Using the vesa-driver the mix stays at 50:50. Using the radeon-driver (dri disabled) the CPU stops using C3. the facts in case somebody already has a idea: - ibm R51 - PentiumM 725 (1.6GHz) - Intel 855PM chipset - radeon 7500 mobil - xorg 6.8.2 - kernel 2.6.11-1-686 (debian stock-kernel) thanks. ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
