So maybe I was derailed with my WDIOF_REBOOT suggestion by the proposal to repurpose WDIOF_EXTERN1 to indicate a regular reboot. I still don't think repurposing WDIOF_EXTERN1 is the right direction. But, perhaps the thing to do for a regular reboot is to not set any reason flags at all? It just depends on whether we're wanting to separate a cold boot from a reboot (as they _may_ behave differently on Aspeed hardware), as on a cold boot we wouldn't set any reason flags either. Andrew
