Walter,

I'd advise going back through and running a "make menuconfig" on 2.6.31-r6/10 and verify that everything is in order.
The reason that I say this is that, in the event that your kernel -DID- revert back to defaults, if you have a non-ext2/3 partition, it isn't going t recognize it (EXT4, Reiserfs3.6/4, etc aren't "default" options).
As for the warnings that you are talking about, those have existed for a while, they are obviously non-fatal and not really pertinent to your issue at hand.

Cheers

Kad

 Today is when running a lilo menu with "production" and "experimental"
kernels saved me.  "production" is 2.6.30-r8.  "experimental" is
2.6.31-r6 or 2.6.31-r10 (same problems with either one).  I set
/usr/src/linux to point at 2.6.31-r6 (or 10), copied .config from
2.6.30-r8 and ran "make oldconfig".  I got the warnings listed below
before the config process started.  "make oldconfig" appears to have
reset to default values, and it was showing me some settings totally the
opposite of what I know I've set.  When I ran through "make oldconfig",
compiled and rebooted, I got a framebuffer console, which I *KNOW* I
haven't selected.  And there was a kernel panic because gentoo couldn't
find the boot device.

 I'm enough of a bit-twiddler that I can set up the kernel manually.
But I know from past experience that it's a long slow process.  Is
there any trick to salvage "make oldconfig", before I resort to setting
up the kernel "the hard way"?  Here's the output from "make oldconfig"
up to where it starts asking questions...
