I can reproduce this as well.

On systems with a single CPU, the failure rate is about 100%
(i.e. it *always* fails).

Note for Andreas or whoever wants to look at this:

To reproduce please try setting GRUB_CMDLINE_LINUX="nr_cpus=1"
in /etc/default/grub first. If that does not work, then please
contact me privately, as I am willing to provide ssh access
to a machine where the failure may be reproduced all the time.

(I'm raising this from normal to important because it's a violation
of Policy 4.2, and also because I believe a fix should be allowed in
a bookworm point release in case nobody fixes it before 12.0).

Thanks.
