Oh interesting. We periodically see this with HP kit, but nothing else
which is why we assumed it was iLO specific. Perhaps it is not after all.
As for suggestions, try manually prodding port 3f8 to see whether the
UART is actually working?
Alternatively, use `xl debug-keys` and `xl dmesg` to see whether you can
provoke it back to life.
