When you say not working are you seeing no more that
HZ interrupts per second? After compiling in you did
enable it with the sysctl?
After recompiling kernel with
and kern.polling.enable=1 number of interrupts shown in systat -v 1 does not
change (about 5k). CPU interrupt load does not changes as well. Also RTT in
ping increases from 2ms to 20ms. After disabling polling RTT goes back to
2ms. So we decided that polling does not work on i82550 in SMP.
