hi,

I was looking at PR 29516, and I noticed that there are lots of places
that it's modifying mp_flags (which is modified in magma_hard())
without blocking serial interrupts.  I fixed that and got rid of some
of those flags that weren't necessary.  could someone look at the patch?
(or better yet, test it?)  the diff is at
