I also tested with xen devel (Xen version 4.15-unstable, Latest ChangeSet: Wed
Nov 4 09:27:22 2020 +0100 git:9ff9705647-dirty).
Your patch is needed there too to avoid the panic.
As with 4.13, I have problems with interrupts not being properly
delivered. The strange thing is that the counter is not 0, but 3 (wuth 4.13)
or 2 (with 4.15) which would mean that interrupts stop being delivered
at some point in the setup process. Maybe something to do with mask/unmask ?
The problematc interrupt in identifed as "ioapic2 pin 2" by the NetBSD kernel,
so it's not MSI/MSI-X (not sure it matters though).
Maybe something related to mask/unmask ?
