   Is the address where it is crashing some sane address? Could you post your 
nuttx elf file, or assembly objdump of the crashing address?
   
   I managed to make a configurarion for mpfs, which crashes in the same test 
occasionally. But I don't know if that is the same issue; my issue seems to be 
entirely timing related and the semaphore patch doesn't affect to it. But now I 
suspect that there is something wrong with signal delivery in SMP. I'll try to 
find the cause for that, and then we can check if it was the same root cause. 
But I didn't find the cause yet, it seems to be some race in sig 
queuing/delivering.
