How useful is this? It could be useful if:
- crash is not reproducable, and
- customer site where we can't access the BMC, and
- system eventually boots so crash dump can be saved, and
- dump is sufficient to debug (i.e., debugging does not involve hardware
I'm a bit skeptical. I reckon we'd get more milage out of changing assert
to trap so we get regs.
