Its very early in the boot process.. and thus no crash dump ;-0 Its in netisr_start_swi() When it initializes netisr_mtx with a mtx_init() it crashes saying that netisr_mtx is unaligned... (the address ddb shows for netisr_mtx ends with c ... so it definitely is unaligned... Looking at the netisr_workstream structure (where netisr_mtx is) it appears to be in theory aligned right (follows 2 pointers)... so did something change the DP_CPU Define stuff to cause us to get unaligned access? Just curious... If I don't hear from anyone I will start backing things out 1 rev at a time until I find what did it I guess ;-) R ------------------------------ Randall Stewart 803-317-4952 (cell)
