This is current on a Beagle Bone Black (dmesg below). Looking at the diff to the previous dmesg (also below), sitaracm(4) is no longer recognized - is that intended? On the other hand, ompinmux(4) is recognized now.
The base system seems to be running just fine with /etc/malloc.conf -> CFGRSU Thank you!
