Younghwan Go,
If you want to build kernel with tboot/TXT support, you should use >= 2.6.33
and set 'CONFIG_INTEL_TXT=y' by "make menuconfig".
Can you check your "root=XXX" in your grub?
I assume you have the following grub menu.
root (hd0,0)
kernel /tboot.gz logging=serial,vga,memory
module /vmlinuz
module /initrd
module /i7_QUAD_SINIT_20.BIN
Try to remove tboot.gz and the sinit to be
kernel /vmlinuz
module /initrd
To see whether you can find the root device?
Thanks.
