Incorrect.  Correctable MCEs should not panic a machine.  Uncorrectable should.

Please do.

Please defer your imagination.

> Also, isn't devd for device removal/insertions?

Not only.  It might have started like that, but now it is almost a generic
mechanism for kernel to userland notifications (e.g. ACPI events).
