      I don't aware if there's something new from Marek who initially worked on these patches. I think at the time he addressed not this particular hardware but rather the global issue, and this patch wasn't tested with Coral HW, so most probably that's why it doesn't work (may be more issues...)

      I will ping Marek on XEN Community Matrix channel to know if there's something new at that level and will keep you posted.

          Just got the answer from Marek on that. The patches he made was tested with Intel Wifi cards and was targeting the similar issue (MSI-x table) but not the same as Coral TPU (PBA). It should be not very very difficult to extend his patches to the PBA, but unfortunately neither him (neither us) don't have this specific hardware.

          The patches he made are actually upstream b2cd07a0447bfa25e96ae13e190225b61a3670cb so you can take a look at it if you want.

          I will try to see if we have an easy possibility to get this HW

            The other way is to build a version that "should work" and make it test by the community 🙂

              @milch I will take a look this week and try to figure out if we can make progress on that, so you could have something to test.

                Hi Guys,
                I'm happy to help. I wouldn't say I'm overly technical but not a noob either.
                I have a clean install with the hardware. I can arrange a remote connection to the machine if that makes it easier.

                Let me know and I'll do my best to assist.

                  @Niall-Con Thank you! I'll take a look to that and will ping you to test on real hardware. Just need to find time (in the middle of storm right now), so it'll take one or two weeks most probably.

                    @andSmv Any news on a test build with the patch? I'm wondering if this issue is related and would love to be able to test.

                      Also ended up here while researching/troubleshooting this hardware; Has there been any additional movement on this topic?

                          Hey, sorry guys. Didn't have time to advance on that. I promise will put something to test during november.
