I've tested 2.6.23 all the way up and the last working kernel is
2.6.27. Here's a picture of 2.6.25 boot failure, but its the same on
2.6.26:

I'm using stock kernel builds for >= 2.6.27 as that is when Ubuntu
started producing mainline kernels, I've built the others which makes
me suspect I misconfigured them. Here's my config on 2.6.26, for
example:

Not sure what it could be.
