I've looked at the ethregs dumps, the good news is it looks like the hardware succeeds to self-init, but on the ethregs-fails.txt did you load the driver? it appears you did not, or at least didn't do # ip link set eth0 up # ethregs > regs.txt also looked at the lspci -vvv information and in both cases MSI was enabled, but in the fails case the value in the data field for the MSI vector is different, which seems a a little strange but I'm not sure if it is responsible for failure if the driver was loaded, and failed dhcp, what happens when you run ethtool -t eth0 offline? when the driver is loaded, and the dhcp fails, can you assign an address manually (and bring the interface up) and have it work? one more thing to note please, can you send cat /proc/interrupts from 10 seconds apart when the driver is loaded and the port is UP, but not working. dhcpcd or dhclient both have a tendency to put the port DOWN after they fail to get address, so thats why you may need to do # ip link command above before gathering /proc/interrupts. is your bios up to date? Thanks, sorry for the delay, lets see if we can figure out what is up.
