If you're not using the gzipped kernel stuff, then the best suspect would be the TFTP client from the bootloader, which is known to be dodgy. Warner worked on this, and you may try your luck in flashing what's in sys/boot/arm/at91 (make sure to replace any occurence of -DBOOT_TSC with -DBOOT_KB9202). Cheers, Olivier
