Actually it looks like use of an already freed pointer. It's similar to
the other port heap issues reported. Interestingly it actually ends up in
0xdeadbeef, which could now come from either heap implementation, the old
heap still used by the port code, and the slab we currently use as kernel
heap. Until now I thought there weren't any 0xdeadbeef's in those KDLs, so
it may point at the slab, seeing that we only introduced 0xdeadbeef there
last week.
