I read it and that doesn't seem to be the problem nor the solution.

The dmesg output does appear when I'm using the SHR-unstable.
It seems that the problem is apparent only with the NOR u-boot and I've tried several ways and I can't flash a new kernel to the NAND.
Forgive me if I hadn't done my homework and looked throughly through the wiki pages but is there a way to flash a new kernel to the NAND through a distribution working on the SD card?
