Warning: lpc_ich: Resource conflict(s) found affecting iTCO_wdt
ACPI OpRegions are conflicting with the same I/O region used by the
lpc_ich driver for the Intel TCO (Total Cost of Ownership) timer
(iTCO_wdt, this is a watchdog timer that will reboot the machine after
its second expiration).
Warning: lpc_ich: Resource conflict(s) found affecting gpio_ich
This again is because ACPI OpRegions conflict with the same I/O region
used by the lpc_ich driver, this time for the GPIO region. Again, I
don't believe this is an issue to worry about.

I don't think this are bugs per-se. The lpc_ich driver uses these I/O
regions that are already reserved by ACPI OpRegions and they seem to co-
exist OK without any issues. The warnings are alarming, but can be
ignored. There's nothing to fix.
