Is this pciconf report from i440FX QEMU/KVM machine rather than a Q35 one ? I have not managed to flip my test VM from Q35 to i440FX as per discussion = in your bug thread yet as I got into large regression build. I am now part way through building new kernel that is 11.3 with mutant most= ly 11.2 networking sub-system. I say mostly 11.2 networking, as I believe that the VirtIO network version = ID bug you identified in combination of possible introduction of defect with changes in the netmap 11.3 code. This is why your fix was not enough and why all the network interfaces are broken not just VirtIO. My mutant 11.3 Kernel + 11.2 Network build got much bigger than expected as= the 11.3 netmap code results in ripple through impact down into all of the driv= er code and also up into the network abstraction layers :-( So when I wound back to 11.2 netmap I have to also wind back on these impac= ts. I am almost there I believe this this "regressed 11.3" custom kernel. If I am right about netmap problem (I hope I am ...), then I can home on the specific issue with this code section. I hope to test soon, after many many builds... Thanks again for your tips and insights. Cheers, John --=20 You are receiving this mail because: You are the assignee for the bug.=
