pussuw opened a new pull request #5919:
URL: https://github.com/apache/incubator-nuttx/pull/5919


   When process a is switched to process b, the address environment
   is swapped with a call to group_addrenv(). The stack upon entry
   will be a's, and upon exit b's. This will fail, so a neutral stack
   is required, either a kernel stack or an IRQ stack.
   
   To me IRQ stack == kernel stack, so make the dependency like this.
   
   ## Summary
   Sanity check
   ## Impact
   None, unless someone uses ARCH_ADDRENV=y without an IRQ stack (which does 
not work as mentioned above)
   ## Testing
   MPFS/icicle:knsh
