Subject: kernel BUG at fs/ext4/mballoc.c:2993!

hello,
I just built a fresh clfs system using the tutorial.. right now Im
able to boot and am able to login, the system seems to be running as
it should except for when I try to install gmp and/or do a /sbin/lilo
I see a message appear on screen(below) then if I do any kind of
command(dmesg > dmesg) I get a stuck screen. has there been anything
similar to the below message?

keep in mind the kernel I'm using is 2.6.35-rc6 which on other
machines(same type of system) run just fine without such message.

only real thing different that I did with this build was build the
latest gcc with gmp/mpfr/mpc inside gcc source directory instead of
installing them on the system then using the switches to there
location.
