Paul got me a testbed and I learned thf ollowing things:

The crazy error message from expect means that it got -EIO while trying
to read(2) data from the ptmx slave file descriptor. It then closes the
fd and gives up.

Causing load on the host CPU makes the issue more likely to reproduce.

In the non-expect variant for debvm (non-efi), I saw the following
error:

qemu-system-x86_64: system/physmem.c:2680: iotlb_to_section: Assertion 
`section_index < d->map.sections_nb' failed.
