Components on fire could be the root cause of many errors. If we really
believe that is a problem we should power the system off rather than
just calling panic() [not just for PCIe errors, but also for machine
checks, and perhaps a bunch of other places in the kernel].
True story: I used to work for Stratus Computer on fault tolerant
systems. A customer once called in with a "my computer is on fire"
report and asked what to do. The support person told them to power it
off. Customer asked "Isn't there something else? It's still running
just fine".
