I believe it won't be needed though, since > the pci logs are practically complete. Sadly, the kern_4.20_debug.log file is incomplete. I would like to at least see it starting from: Jan 8 22:57:51 picolo kernel: [ 6.792819] mvebu-pcie soc:pcie: MEM: [mem 0xd0000000-0xefffffff], IO: [io 0xffe00000-0xffefffff] (this line from the reverted log, but I'd like to see it in the non-reverted log as well) Thanks!
