How to solve boot problems with Ubuntu after kernel upgrade

Hi all,

This may not apply to any of you guys here, but if you encounter a strange problem where initrd.img fails to be rebuilt properly after a kernel update and you end up missing the right modules for your hardware, resulting in a failed boot and dropping down to busybox shell in initramfs, then read on:

Super geeky, but who knows, some of you may need it.

Mrk

 

Thanks, Mrk, very useful! I haven't run into this problem so far - but who knows ...

 

There's always the first time. I've seen quite a few threads on Ubuntu forums with people complaining about this. Hopefully, it should help.

Oh, there's an official bug, too.

Cheers,
Mrk

 

Hi Mrk,

Have you heard about KSplice, i.e. adds kernel security updates without having to reboot the Ubuntu kernel. Here is a link from Ars Technica:
Ksplice: Update computers without rebooting

Started playing with it ... nothing major.
Will get to it eventually ...

Thanks Mrk. Have saved the article since I have been upgrading the kernel on Jaunty up to 2.6.31-1. Since I have been playing around with kernel upgrades I really haven't had any major problems, but it is good to have some documentation handy just in case. By the way, 2.6.31 is rockin' here.
