If you have a serial console you can probably get output on that. If you have flipped EMBEDDED to Y then you might also have to enable EARLY_PRINTK. Another trick might be to turn set BOOT_PRINTK_DELAY (Kernel hacking -> Delay each boot printk message by N milliseconds) to something like 2000 and see if you can read/catch the messages before the kernel reboots... Failing that start a git bisection ( http://www.kernel.org/doc/local/git-quick.html#bisect or http://www.stardust.webpages.pl/files/handbook/handbook-en-0.3-rc1.pdf ) from the last good kernel... -- Sitsofe | http://sucs.org/~sits/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
