Doesn't reproduce here.

Running "while true; do dmesg; done" on the virtio-gpu fbcon.
Running the pps fork bomb on the serial console.

Can watch dmesg printing the kernel messages over and over, until the
shell can't spawn dmesg any more due to the fork bomb hitting the
process limit.  No BUG() triggered.

Tried spice, gtk and sdl.

Hmm.

Any ideas what else might be needed to reproduce it?

cheers,
  Gerd
