#67504 — Bug#964734: same problem with newer kernel versions

FromBernhard Turmann <bernhard@turmann.eu>

In reply to#67497
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.

Regards
Berni

SubjectBug#964734: Confirmed workaround: enable MSI
Message-ID<ANxj3-Hg-1@gated-at.bofh.it>
In reply to#67504
After enabling MSI within /etc/modprobe.d/ the card is working as expected:

 options ddbridge msi=1

Upstream bug report has been updated accordingly.
