Hi, I turned the debug level up to 4 on our smaller (128k) ROM downstream build and seem to have hit a case where it's been layed out so that the 'ExtraStack' is at the same location as some code (display_uuid) which was causing some very random behaviour;

Would this be consistent with a stack overflow?
See commit 46b82624c95b951e8825fab117d9352faeae0ec8. Perhaps BUILD_EXTRA_STACK_SIZE (2KB) is too small now?
The ExtraStack isn't used at the point Dave reports the problem - display_uuid() is part of the init phase and that happens on the main "post" stack.

I missed that earlier - there were some important fixes post 1.9.1 wrt reboots. Commits b837e68d / a48f602c2 could explain the issue. I'd make sure the issue is still present on the latest version.
