in any case, I'd need some more information:
the link to your .config is broken, I only get an empty page.
if the kernel is involved, output of dmesg and rc.log would
be needed to.

by the way, did you anything with your ACCEPT_KEYWORDS?
if not, the best thing would be set it simply ="" (and
afterwards --update world, --depclean and revdep-rebuild),
but that's up to you.

please send me the requested information, otherwise it's
difficult to find out what's wrong.
