Hi Conor, sorry for dropping this on the flor. I was at LSF/MM least week and my plan to go through my backlog today didn't go to plan as I unepectedly spent half the day at doctors appointments. The commit looks like a somewhat unusual culprit for a boot failure, so any chance you could do another manual verifiation pass where you checkout 6424e31b1c05 and then the commit before it (i.e. as git checkout 6424e31b1c05^) to make sure it really is this commits? Some of the commits around it just seems like more likely culprits to me, so I'd like to really be 100% sure here. In the meantime I'll look through the patch. Also you don't happen to have earlycon support on this plaform to see if there are any interesting messages on the serial console?
