Hi Daniel,
Please file a QEMU bug report here (or just reply to this emails with
details on how to reproduce the issue and I'll file the issue on your
behalf):
https://gitlab.com/qemu-project/qemu/-/issues

We can also wait until your Linux patches have landed if that makes it
easier to reproduce the bug.

Thanks!

Stefan
