Bug#964734: same problem with newer kernel versions

[Bernhard Turmann]

FTR, the problem stays the same also with newer upstream kernel 
versions, tested:

- 5.8.0-rc4
- 5.7.8
It always works with reverted commit b88bf6c3b6ff ("PCI: Add boot 
interrupt quirk mechanism for Xeon chipsets")

See more details in the upstream bug report.
