Random kernel panic (2/3) in github macOS runner: IO-APIC + timer doesn't work!
<!--
This is the upstream QEMU issue tracker.
If you are able to, it will greatly facilitate bug triage if you attempt
to reproduce the problem with the latest qemu.git master built from
source. See https://www.qemu.org/download/#source for instructions on
how to do this.
QEMU generally supports the last two releases advertised on
https://www.qemu.org/. Problems with distro-packaged versions of QEMU
older than this should be reported to the distribution instead.
See https://www.qemu.org/contribute/report-a-bug/ for additional
guidance.
If this is a security issue, please consult
https://www.qemu.org/contribute/security-process/
