NetBSD [hostname redacted] 10.0 NetBSD 10.0 (GENERIC) #0: Fri Dec 13 12:47:00 UTC 2024  root@[hostname redacted]:/usr/obj/sys/arch/sparc64/compile/GENERIC sparc64

>Description:
I took g/usr/src/sys/arch/sparc64/conf/GENERIC and simply enabled DIAGNOSTIC,
rebuilt the kernel, booted and ... reboot after initialising the audio drivers.

Annotated dmesg, both the failure and successful both with unmodified GENERIC afterwards:

>How-To-Repeat:
Take GENERIC, enable DIAGNOSTIC, boot the resulting kernel on a SUN Ultra-45.
I strongly suspect this to be enough of a driver issue that one is unlikely
to hit this with either qemu or different hardware - my SUN V100s (UltraSPARC-IIe @ 548 MHz) run 10.0 with a lightly modified GENERIC and DIAGNOSTIC turned on without exploding on boot.

I'm happy to accept, build and boot exploratory patches and report back.
