I can't speak to the specifics of the driver, as I neither use it nor have any if_rl hardware. However, you should know that because debug.mpsafenet=0 also changes quite a bit of timing, not just lock coverage, it's not necessarily a locking problem. Out of curiousity, if you take "options PREEMPTION" out, but leave debug.mpsafenet=1, do things change? Robert N M Watson
