Hello,
I have a system that should keep the hardware watchdog active while
rebooting the system. It has worked fine up to systemd version v254.
I noticed that since systemd version v254 my system stops the hardware
watchdog after systemd-shutdown completes. I think it's the
watchdog_free_device function that's responsible.
The watchdog_free_device function will call watchdog_set_device(NULL)
from watchdog.h. Since commit f81048f8 the watchdog will be disarmed and
stopped if changed in watchdog_set_device.
There's a comment just above watchdog_free_device in shutdown.c that
contradicts what's actually happening right now: "Note that the watchdog
is explicitly not stopped here".
Is this the intended behavior? Anything I can do to get my system back
to its behavior before version v254 where my hardware watchdog is still
active/running after systemd-shutdown has finished?
Best regards,
Andreas Svensson
