Hi,
did you create a /dev/console device node ?
crw------- 1 root tty 5, 1 May 25 07:36 /dev/console
Even, if you are working with udev, you have to create this mode manually, because its needed at an early stage of the init process.

Subject: console problem while initializing form ramdisk
Hi,all
I am trying to run linux2.6 on Xilinx ML403.I have builded and loaded zImage.initrd.elf successfully into the board and when the kernel was booting to the point initializing form ramdisk,I got the problem as follow.
loaded at: 00400000 0063213C
board data at: 00630124 0063013C
relocated to: 004050E8 00405100

I configured bootloader like this:

I don't know where the problem comes from and how to solve it.
Any help from you is appreciated.Thank you!
