Can you quickly check if you have the right phy id written in your platform file for your board?

	Hi, 
	
	Downloaded 2.6.16.26 and booted up and got this : 
	
	/ # ifconfig eth0 172.28.8.254 up 
	[   34.034596] 0:00 not found 
	[   34.037330] eth0: Could not attach to PHY

	SIOCSIFFLAGS: No[   34.044526] eth0: Could not attach to PHY 
	 such device 
	SIOCSIFFLAGS: No such device 
	
	I had enabled all the PHY devices in .config and also tried only with Marvell phy enabled.

	It looks like your 2.6.12 kernel isn't handling the PHY correctly.   
	I'd recommend upgrading to something newer which has the phylib  
	(can't remember which 2.6 that went into).
