I loaded the design specs for this and confirmed this does support MSI, so I don't think this is a long term solution. I do have a spare one of these c= ards (I think it is the same chip), and some kernel development experience, but = none with PCIe.. I am willing and able to work on the correct solution, I will = just need some guidance. (I will first experiment with removing the limit on the number of MSI interrupts) --=20 You are receiving this mail because: You are the assignee for the bug.=
