SUMMARY: High sys cpu time on second processor

From: <>

Several people pointed me at problems with high numbers of interrupts
meaning it was liable to be a 'hardware problem'.

lockstat -kgIW -D 20 -s 40 sleep 5
pointed me at interrupts being generated by several things, all of which
prefixed "se_".

Also of use is the 'prstat' command, in this case used with '-C' to examine
processes on each processor.

Having now disconnected the serial port, this machine is now behaving
normally.We'll be investigating that further to see exactly what is causing
that problem.
