Hi, I have been trying to hot-add a PCIe bridge and getting the following message in dmesg: No bus number available for hot-added bridge 0000:06:00. The kernel is 4.4. Do we have any patch for this? I tried Yinghai's for-pci-busn-alloc patch. Did not work. Not sure I picked up the right changes. Any input...
