After above message there are no any messagess were displayed.
It look like kernel hang somewhere before doing the serial UART0
initialization.
I put fiew code like setting GPIO18 to high and low in preodically to see
whether the kernel is running, but there were no change in the state of
GPIO18.
Followings are the Yamon enviremnt variables

-----------------------------------------------------------------
please tell me wether I should apply any patches to this Linux-2.6.16 kernel
to make it works with db1100
I have tested db1100 board with linux-2.4.20 in the same way there it works
fine.
I want to move to linux-2.6.
please suggest me any good working linux-2.6 kernel release with db1100.
Thanx

There is some vital information missing from your email. Can you
also send the yamon command's you use to start the system. Like for
instance the output below is far more complete than yours. I have put some
extra comment in between '->' and '<-' to give you an idea what is
happening.
-> Here yamon starts and shows some general information <-

CPU revision is: 02030204
AMD Alchemy Au1100/Db1100 Board
(PRId 02030204) @ 396MHZ
BCLK switching enabled!
Determined physical RAM map:
memory: 0c000000 @ 00000000 (usable)
Built 1 zonelists
Kernel command line: ip=192.168.10.236

-> I have cut out the rest for brevity <-
So there can be two things:
a) You forgot to start the loaded kernel. (this I can't tell
from your output, so please make it more verbose)
b) Can it be that you have disabled CONFIG_PRINTK in the kernel
configuration???
