   > @xiaoxiang781216 since it appears that you are actively using SMP on the simulator,
this bug must have been fixed with some of your previous changes. In that case, the bug should
be removed from the TODO list.

   Yes, SMP issue is fixed by this patch:
   commit a87271617a5e05c02d160803f43c4d644ebb45db
   Author: Xiang Xiao <xiaoxiang@xiaomi.com>

       arch/sim: Replace pthread mutex with atomic function for up_testset
       
       up_testset may be called from signal hander but it isn't safe to call pthread API in
that context
   
   Both ostest and smp can run sucessfully now.
