Right, so Tony meant last time we were talking about it that nvram is
too slow for collecting the whole dmesg into it (could mess up timing
and such - although, come to think of it, we do have CONFIG_PRINTK_TIME
so we can sort them if they're out of order...)
So what I'm questioning is whether a single oops/panic can be written
out to nvram reliably too?
Because if not, then the problem we're trying to solve is moot and
beside the point - maybe we should not use EFI as a pstore backend in
irq context at all?
I'm just putting it on the table so that we have talked about it too,
before devising a solution.
