Description ken73.chen 2015-02-16 16:20:06 UTC
Created attachment 153039 [details] dmesg, devinfo, pciconf output when with options NEW_PCIB After an old server upgrading from 8.4 to 10.1, em0/em1 and ahc0/ahc1 can not work with GENERAL server because 'can't allocate register resources'. 'hint.agp.0.disabled=1' and 'hw.pci.realloc_bars=1' are not helpful for my server. After add 'nooptions NEW_PCIB' to new kernel, em0/em1 and ahc0/ahc1 both come back. I attach dmesg, devinfo and pciconf output.

After installing 10.3 on a FSC Futro S-550 thin client to work as a router, network cards in the PCI riser slot were not detected until NEW_PCIB was found in /sys/amd64/conf/DEFAULTS and commented out.
