I Just tested to upgrade from ros 5.20 -> 6.03b i noticed that i lost my ethernet interfaces, they are quite old so im wondering if they are not supported annymore ,
forgot to mention that while i can see them, they dont work , eg if i do a /interface ethernet print , the router hangs and have to be rebooted

If anyone is looking for confirmation that this is an issue I have the same issue on my x86 board
none of the ethernet interfaces showed but the wlan did.

below is a copy of the PCI when i reverted it back to 5.X

i get this also. i upgrade from 6.0b2 to 6.0b3

this issue is also present in rc1

I confirm. Looks like RTL8111 is not supported in RC1

RTL8111 driver missing in 6rc2 2012.10.12 x86 as well. Supouts submitted to Support as test reports

I had access to the router over other interface + backup before test upgrade so I was able to restore previous version in 3 reboots.
