Some system admins prefer to have everything on dmesg, as they
can enable a serial console, and catch the logs remotely, even
when the machine crashes for example due to a hardware failure.
So, IMHO, one feature that the perf event needs is the capability
to report errors via a serial console also, or a mechanism where
some events are sent via dmesg.
