   That's curious. Unhandled Exception number 1 is a debug exception, this is out of the scope of NuttX. I'm not sure how this can happen during `ostest`.
   I'm running ostest now, but can't hit the issue.  A backtrace would help to know when that happens but we would need to add something similar to: https://github.com/apache/incubator-nuttx/blob/master/arch/xtensa/src/common/xtensa_user_handler.S#L192-L202 to link the pre-exception frame.
   
   Unrelated to this, but some defconfigs may need to change their stack sizes since now we have the FPU as part of the stack, I did see some stack corruptions during testing.
