------- Comment #13 from [EMAIL PROTECTED] 2008-12-02 06:47 ------- Here are my investigations with powertop: kernel 2.6.27.7, limited to C1 state: If I dont move anything, the most wakeup events come from the b43 w-lan driver which IMO seems normal. Type something on the keyboard or move mouse/touchpad causes many wakeups.. I guess this is normal too. with parameters "processor.max_cstate=9 nohz=off" : Powertop shows that C2 and C3 states are "available" but never uses them... I dont know when these states should be running but I also tried to run the Laptop from battery and turning of the ondemand gouvaneur and forced the CPU to run with 2GHZ (maximum).... only C1 state is used but again I dont know enough about these stuff so I could be totally wrong. with "processor.max_cstate=9" only: system boots slow, and freezes during init ... no chance to do investigations there. MAYBE the nohz feature forces the CPU to enter C2/C3 states, which cause the system to fail ? But strange that it reports that these states are available... thats all I could say now, I hope that helps in some way greetz, Matze -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
