Sorry for insisting but can anybody help out? It was working up to

Reverting this 2017 patch over master fixes the issue but the changes 
are unrelated to the driver:

$ git show --stat=60 bc976233a872 | grep \|
  arch/x86/kernel/apic/vector.c | 12 +++++++-
  kernel/irq/msi.c              | 37 ++++++++++++++++++++---
