The reproducer you have is accurate.  Is there anything else you need from me?

According to comment 2, this was already fixed by the rebase to QEMU 8.0, so I don't think there is anything left to do from the development side.

Mirek, can this be moved straight to ON_QA or do you still need to do something else to document that it was fixed in a build?

QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass
