Dear Friends, we have a custom board based on PPC405EP processor, this design is based on bubinga reference board. we have ported u-boot 1.4 and linux kernel 2.4.32 - this design is already in production for several months recently, on few boards we started seeing "eth0: WakeUp interrupt !" message while linux bootup(to be specific when ethernet driver is loaded). but this problem is sort of intermittant in nature, out of 5 reboots, once or twice "eth0: WakeUp interrupt !" keeps printing on terminal without proceeding any further....
can anyone give me a direction why this happens? Thanks for your support, Albert. following is the boot message from my target board, U-Boot 1.1.4.1.4 (Dec 5 2007 - 17:22:12) CPU: AMCC PowerPC 405EP Rev.
