I used r255420 as the = build platform and was able to upgrade to r255586 on my Raspberry Pi. Here are some observations: 1) For some reason this same upgrade failed on my BeagleBone Black (also = running r255420).

I have noticed problems with = the system when swap is used. Paging out to swap seems okay, but = processes appear to die when they are paged back in from swap. = Sometimes, this hangs the system. 3) FWIW, I am running with super pages enabled: vm.pmap.sp_enabled=3D1.
