Hi,
I have been compiling my own kernels since ages and switched from 2.6.32.8 to
2.6.33.2 now.
Same procedure like allways - copied .config to new buildtree, make menuconfig
(almost nothing changed in config), installed the new kernel on 2 machines.
The 2.6.33.2 kernel works fine on a "Pentium(R) Dual-Core CPU E5200 @ 2.50GHz"
but on the Atom (Fedora 12) it does not even get to the "uncompressing Linux kernel"
message (I have early printk and such). No Grub error, just blank screen with cursor,
alt-ctrl-del does not work and power does a hard power-off immediately. Booting
other kernels still works, boot partition is 48% full, all image sizes etc seem
fine.
So I am really puzzled.. did anything get changed into the very early boot
sequence?

Oops, that's the problem, you need to do 'make oldconfig' to ensure you
didn't miss anything, and to adjust any new defaults.
Have you tried that?

did not tried that yet. Although it is possible to miss something with menuconfig
I did diff the .config files without noticing anything obvious.
Meanwhile I have tried a few recent Fedora-12 kernels and none of them worked on
this particular Atom Netbook with which I have never had problems before.
With the Fedora kernels the issue appears to be Intel graphics and it seems the boot
continued when I blindly typed the dm password.. so I will investigate further.
Last Fedora kernel that worked was 2.6.31 based, the 2.6.32.* I tried so far will
display a black screen.

I can confirm that "make oldconfig" does not fix the problem.
Grub appears to load the kernel (at least it does not come back with an error as it otherwise
would), cursor in the topleft corner and absolutely no activity.
no reaction to ctrl-alt-del or magic keys. For all other kernels I would see at least the
"uncompressing kerne.." message, not here.

Try asking on a Fedora kernel list as this might just be a config issue
with the way modesetting is set up.
good luck,

it is a clean kernel.org kernel, with early printk and I tried playing with
various (no)rhgb noquiet options just to be sure. So this does really appear to
be something that happens in the earliest bootstages before uncompressing and
can not think how it could be Fedora's fault - it does not get anywhere close
to touching the initramd image.
The only way I can proceed is try some kind of bisecting.. real bisect won't
work as the wlan connection is painfully slow with the only working kernel
taht I have installed on that computer.
Btw I have filled a Fedora bug against a 2.6.32.11-fedora kernel with broken
kms but afaics this appears to be totally unrelated.
