Hi, I'm having Problems with the gianfar Ethernet. eth1 is working fine, but eth0 is making trouble. It's making trouble in u-boot as well, so it could as well be a hardware problem. First of all eth0 receives some frame errors (frame: in ifconfig), but eth1 doesn't. eth1 performs well under a ping flood, but eth0 produces the following WARN_ON() after some time. I'm using linux-2.6.26 ARCH ppc on a MPC8347 with 2 different 100MB PHYs.
Is my Board just triggering this error or responsible for it?
