Currently, sparc64 SMP panics before getting out of single user mode because there is an optimization case in cpu_switch() (if we are switching back to the same thread, we just return right away) that doesn't set td_state to TDS_RUNNING. Also, according to Peter, the code in ia64's cpu_switch() doesn't work either. Rather than try to fix this in the assembler though, I think it is easier to just set the thread state once in C at the end of choosethread(). It is a lot easier to maintain down the road. The patch to do this is at http://www.freebsd.org/~jhb/patches/kse_switch.patch
It has been tested on sparc64, alpha, and i386 all with SMP. I would like to commit it soonish.
