[U-Boot] U-boot resets when booting Linux kernel

[Simon Boman]

Hi!

I'm trying to install a Linux kernel 2.6.22 on my U-boot git from October 2008.
It look like this:

=> bootm fc010000 - fc008000
## Booting kernel from Legacy Image at fc010000 ...
   Image Name:   Linux-2.6.22
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    773524 Bytes = 755.4 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
## Flattened Device Tree blob at fc008000
   Booting using the fdt blob at 0xfc008000
   Uncompressing Kernel Image ... OK
   Loading Device Tree to 007fb000, end 007fff5a ... OK
Resetting the board.

And then U-boot has restarted. I have set "autostart no" but still it
is rebooting.
When my ethernet interface doesn't work I am using the serial
interface to transfer the linux kernel image and save it to the flash.

Any suggest why U-boot act like this?

TIA
Simon
