[U-Boot-Users] 405Gpr timer interrup

I have a new problem that I am trying to solve - up until now I have not noticed that the timer interrupt has not been working with my 405GPr and u-boot. I just discovered this problem because we recently connected a phy to the 405, and I am now trying to perform a "tftpboot" - I see a message that one ARP packet goes out, and then the board just sits there with no further output - I expected at least a timeout message, and there is indeed a timeout in the code that is supposed to occur if a proper response to the ARP is not recieved within some period of time.

So - the problem I have is trying to figure out what could be wrong with the timer. Could you please advise me as to where I can start?

Thanks
