Did you use the cpufreq driver? I guess the freq was stuck on a very low frequency, but I just checked my 2.6.37-rc1, no such problem(I didn't enable the wireless....) you can check this via this command: $ watch cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq or use the powertop tool. and a possible cause is you may used the powersave mode of the cpufreq driver, powersave will put the cpu into the lowest frequency, then ... so, check it and use ondemand(for pc) or conservative(for laptop) or performance(highest freq) mode instead, you can change the mode: Check which one are you using: $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Change it: $ echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Another potential cause is the bfs scheduler, in 2.6.37-rc1, no bfs added, but currently, bfs is added into our 2.6.37 branch by default. If bfs is the real cause, we may need to revert it. To Shiwei: did you get this problem on your netbook when you resume from hibernation?
