Do you see any messages when you do a post mortem dump of the log_buf memory? [See http://www.denx.de/twiki/bin/view/DULG/LinuxPostMortemAnalysis]

I think I don't understand something in your explenation of post mortem, how can I do grep log_buf system.map when I have nothing but UBOOT prompt?
You do have a development system which you used to compile and link your Linux kernel, don't you? And you do have the "grep" command installed on that host, right?
The GMANE archive _is_ searchable.
What is the GNAME archive?

[Why didn't a google search for "gmane u-boot" return useful links for you?]
I still do not understand what do you mean by init sequence of SDRAM, If I had any hint of what you mean by that I would check for it.
Read the documentation provided by the manufacturer of your RAM chips. It shosuld contain a section about the SDRAM init sequence.
Did you read the FAQ? How about the "clocks_in_mhz" setting? Or the bd_info structure used by the Linux kernel?
Yes, I have thought about the clock value and made sure it is passed Ok, since I am using kernel 2.4.25 I understand that the clock should be in Hz and that is what U-boot transfers.
And what about bd_info?
