Hi Ming,
It’s not obvious to me what the problem is as I don’t see any driver failures. Have you tried using a ramdisk and then seeing if the network is working before using NFS root? And I’m assuming you have used the NFS root before so you know that it’s good for sure. I test on the ML405 with NFS root and haven’t seen this problem, but my setup is a little different. I use DHCP rather than a static IP, but other than that it’s similar. I’m assuming that you accidentally got 2 different powerup outputs in the message below as the 1st stops and a 2nd starts in the middle. How long has it been since you pulled from the Xilinx Git tree? Thanks, John ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of MingLiu Sent: Tuesday, April 01, 2008 8:12 AM To: linuxppc-embedded@ozlabs.org Subject: xilinx Ml405 NFS mount problem Dear friends, I am bringing up my kernel from Xilinx git tree.
