OK, I'll bite - how can the kernel go into a reboot loop that doesn't get to the grub menu? (Hint: How does your system get from the BIOS splash screen to starting the kernel? :)
That's not biting. Having to pointed out when I say something ridiculous is one of the reasons I like the kernel mailing lists so much. Re-reading my original comment in your response makes it bleedingly obvious that what I said was ridiculous. I must have been selecting the broken kernel in grub for it to boot - I still don't remember doing so but it wouldn't be the first time my memory has bent reality.
(Though I've seen kernels that flash the screen like they're rebooting but they're actually hung in a loop, and I've heard some great bar stories about kexec/kdump gone horribly astray and re-invoking the current kernel rather than the kexec target kernel....)
I appreciate your response Valdis, you always take the time to answer nood questions. thanks, Tobin.
