We need to figure out why it doesn't work. I need to see the output of "mptable -dmesg", either from a current UP kernel or the previous working SMP kernel. Also, did you remove ?SMP_TIMER_NC" from your config? And did you change smptests.h in any way? -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
