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". -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
