imx28evk and eth1

Hello all-

I'm using the i.MX28EVK, and I'm having a hard time bringing up the second NIC consistently. I initially ran into this was the ltib build I made, but then I grabbed the included Linux SD card, and it results in the same behavior. The frustrating thing is that every 4-5 boots or so it works (using the reference image), but the rest of the time it doesn't. When it doesn't work, I get the following in the serial session (from the reference image marked "MX28EVK Linux 110-77224 Rev c"):

/***********************/

eth1: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=0:01, irq=-1)
PHY: 0:01 - Link is Up - 100/Full
PHY: 0:01 - Link is Down
PHY: 0:01 - Link is Up - 100/Full
PHY: 0:01 - Link is Down
PHY: 0:01 - Link is Up - 100/Full

/***********************/

I thought for a while that it might be a hardware issue, but the the Windows CE reference build works every time I boot it. Any suggestions?

Forgot to mention, eth0 comes up fine in all cases, just eth1 that is troublesome

I'm having this same issue. I'm testing with the standard 2.6.35 images from Freescale, booting from 4 GB SD card.

I boot the board, and then log-in via the debug serial port. To start eth0 and eth1, I issue the commands:

udhcpc -b -i eth0

udhcpc -b -i eth1

We have two imx28evk boards. On one board, it works fine. On the other board, eth0 works, but eth1 endlessly prints:
