I filed this bug about recent Linux hanging very rarely when booting on recent qemu:
https://gitlab.com/qemu-project/qemu/-/issues/1696 As I'm able to reproduce this bug at will (albeit I have to wait for 100s or 1000s of iterations of the test), I am able to observe the qemu process after it hangs. Is there any information which is useful to collect from the hung qemu, such as stack traces, etc? I know how to collect a stack trace, but if there's other information please give me a guide about how to collect that.
