------- Comment #3 from [email protected] 2009-02-09 02:24 ------- BTW I'm running a 64bit kernel and I removed everything from the .config that I consider unnecessary. Can the issue lie in my .config? > From the /proc/timer_list it seems that the idle_sleep time on CPU0 is far > less than that on CPU1. It is. I was surprised too when I saw that. Though there was no load in the system at the moment (I stopped all unneded daemons). $ ps auxww USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.2 0.0 3624 576 ?
