Running tests on ~yesterday's -current (amd64 running under UTM on
macOS), and this is the last thing I see:
x86_fpregs_xmm_core: [0.076360s] Passed.
x86_fpregs_xmm_read: Connection to nbt.local closed by remote host.
The console said:

As you can seel the crash dump failed, or rather hung, part-way through
and QEMU went into a multi-CPU spin burning about 5-6 CPUs worth at 100%
(the VM has 8 vCPUs assigned). Savecore recovered what there was, but
it's not usable, at least not with crash(8).
