Re: [tboot-devel] How to build old kernel with CONFIG_INTEL_TXT

[Younghwan Go <yh...@ka...>]

  Hi.
I could compile the patch on kernel 2.6.30 successfully without any 
conflicts.
So I ran tboot with this grub menu list:

kernel    /boot/tboot.gz logging=serial,vga,memory
module /boot/vmlinuz-2.6.30-custom root=UUID=.....   iommu=on ro quiet 
rhgb splash text
module /boot/initrd.img-2.6.30-custom
module /boot/i7_QUAD_SINIT_20.BIN
quiet

Tboot ran successfuly and transferred control back to kernel.
Then error showed up. This is the error message.

Gave up waiting for root device.   Common problems:
- Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/1099bffc-45c7-4733-aafc-2abaac6b507 does not 
exist. Dropping to a shell!

Can someone help me what the problem is?
Thanks
