That's not quite true. Many hardware failure-type panics look the same (a
machine check exception panic, an NMI due to a hardware error (this has a
unique panic message), or panics in pmap_remove*() on x86 cover the vast
majority of them). My previous employer actually did track panics using a
script like crashinfo, and I was able to categorize known panics by looking
for signatures in stack backtraces or other panic messages.
