It looks like pcib12 and pcib13 in FreeBSD should be the bridges that have the NVMe devices behind them, but those devices aren’t showing up. I don’t see any obvious code in linux to handle those bridges, so there must be something subtle that we’re missing in FreeBSD. Maybe we’re having trouble enumerating above PCI bus 128? I think that was a problem a few years ago but I also thought it was fixed. Can you do the following in FreeBSD:
pciconf -lBc pcib12
pciconf -lBc pcib13
Thanks,
Scott
