Thanks! # sysctl -a | egrep -e 'cx_(usage|support)' dev.cpu.0.cx_supported: C1/1 C2/1 C3/57 dev.cpu.0.cx_usage: 100.00% 0.00% 0.00% dev.cpu.1.cx_supported: C1/1 C2/1 C3/57 dev.cpu.1.cx_usage: 100.00% 0.00% 0.00% With anything except "C1" the CPU is obviously too slow to do anything useful :-)Received on Sat Jul 19 2008 - 20:52:06 UTC
