[U-Boot-Users] 405Gpr timer interrup

my enet port status shows - "100 MBit/sec, full duplex"
so I think that is a-okay -

Still can't figure out why I'm not getting a timer interrupt

We had a very similar problem with our Ebony system with a single ARP
request going out and
nothing happening after that (but we didn't concentrate on timer issues). It
out our problem was with our ethernet drop from the "wiring closet". U-boot
something to the effect of "10 MBit/sec, half duplex" for the status of the
enet port.
When we change things to "100 MBit/sec, full duplex", everything worked OK.
What does your enet port status show?
