Please don't top-post. Did you add "earlyprintk" to your kernel command line like the EARLY_PRINTK menuconfig help text suggests? arch/arm/mach-at91/include/mach/debug-macro.S also suggests the LL debug output goes to AT91 debug unit not to normal UART (not sure about this, I don't know much about AT91). Did you try to dump __log_buf using JTAG? HTH Johannes
