Comment 7 for bug 1769189

I've tried bisecting a few times, but since my reproducer wasn't reliable enough, I didn't identify the issue. (I see a bisect reported on qemu ML which seems like a bogus result, similar to mine).

In my case, after the "hang", Windows 10 resets the ahci device after 2 minutes and it continues on until another hang happens. Seems fairly random. I increased the number of vcpu's assigned which seemed to increase the likelihood of the hang.

I also went so far as to instrument an injection of the ahci interrupt via the monitor (total kludge, I know), and the guest did get out of the hung condition right away when I did that.
