Basically because you do not have access to IO during the early boot. The easiest debugging solution is to enable CONFIG_DEBUG_LL and throw a printascii(printk_buf) into printk.c, after vscnprintf. That might get you some boot messages through the serial port (if it's implemented it correctly.) -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
