Watchdog ACPI
Event
Shutdown
Restart
Select the operating system event that is initiated by the watchdog ACPI event. These options perform a critical but orderly operating
system shutdown or restart.
Note
In ACPI mode it is not possible for a “Watchdog ACPI Event” handler to directly restart or shutdown the OS. For this reason, the congatec BIOS
will do one of the following:
For Shutdown: An over temperature notification is executed. This causes the OS to shut down in an orderly fashion.
For Restart: An ACPI fatal error is reported to the OS.
Additionally, the conga-TCA module does not support the watchdog NMI mode. COM Express type 6 modules do not support the PCI bus and
therefore the PCI_SERR# signal is not available. There is no way to drive a NMI to the processor without the presence of the PCI_SERR# PCI
bus signal.
