System: NetBSD Hochstuhl 9.2_STABLE NetBSD 9.2_STABLE (RADMINDSRV) #0: Fri Dec 3 23:14:58 CET 2021 hf@Hochstuhl:/var/obj/netbsd-builds/9/amd64/sys/arch/amd64/compile/RADMINDSRV amd64

>Description:

	On an amd64 server (Supermicro H8DCL-iF board, AMD 4226 cpu),
	I enabled the IPMI watchdog.

	Unfortunately, while the wdogctl rc.d script runs very early
	during the boot (BEFORE: fsck_root), IPMI takes its time:

[   1.0470319] ipmi0 at mainbus0

[...]

[   7.6848901] init: copying out path `/sbin/init' 11
Tue Dec  7 17:11:51 CET 2021
Starting watchdog timer.
wdogctl: WDOGIOC_SMODE: No such process
/etc/rc.d/wdogctl exited with code 1

[...]

[  13.0963472] ipmi0: ID 32.1 IPMI 2.0 Available
[  14.4068159] wm0: link state UP (was DOWN)


	
>How-To-Repeat:

	Configure IPMI watchdog on a Supermicro H8DCL-iF board.
	Reboot, see the watchdog fail.

	
>Fix:

	Run rc.d/wdogctl later, or kick IPMI in the pants?
