(off topic for the u-boot list; this is a Linux problem. You really should ask on the arm linux mailing list)
Technically it's a kernel panic (the kernel doesn't know what it should do, so it stops). It cannot mount the root filesystem image that you've given it. Throwing an exception is something else.
What format are you using for your initrd? ext2? Do you have the filesystem configured into your kernel?
Cheers, g.

As mentioned before, this is off topic here.
A few comments anyway:

Uou boot with a ramdisk image...

For an uncompressed image the size if very small. Are you sure this is OK?

This kernel version is extremely old. You will not find much support for it any more.
Kernel command line: initrd=0x30800000,0x200000 root=/dev/mtdblock/2 init=/linu0
You boot with a ramdisk, but put the root file system on a MTD device? Strange.
The "/dev/mtdblock/2" suggests that you are attemptiong to use devfs. IMHO not a good idea.
Also, the "init=/linu0" is strange.

Your kernel seems to have a bug when printing the serial port names.

Are you sure there is actually a root file system in your MTD partition?
