Hi Folks, I have a difficult problem I am stuck with, we had ported LOCK_PROFILING t= o FreeBSD 6.1 and is working fine on mips, but fails miserably on i386. Just enabling lock profiling by the sysctl causes the cpu to reset. root@bcdcpu3% sysctl debug.lock.prof.enable=3D1 debug.lock.pr? << cpu resets here Has any one seen similar issues? Any pointers on where to start debugging this issue? The suspicion is that the spin-lock is perhaps contributing to the problem, but have not been able to get to the bottom. Thanks, Pramod
