It can be called from atomic context, e.g. when switching to console for panic output.

Is this only special cases like a panic - if so can it not be called in a way that distinguishes between normality and nasty cases.

No idea, to be honest. It's an ATOM BIOS interpreter opcode, so in theory it could be indirectly called from anywhere that uses ATOM BIOS.
