Re: [tboot-devel] Problem in desktop display with TBOOT & Custom Kernel (FC13)

Hi, Symptoms - When i boot the system using new kernel and tboot, I am not able to see my desktop/display. It shows lines/boxes. You can not see anything at all. When it boots i can see TBOOT: messages after the boot process, nothing is coming up. So i can not do anything, just need to hard boot the system. The last two boot options of my grub.conf do not work and having problems as described above. System is sierra, and original kernel is 2.6.33.1-24 FC13. T kernel source which i used to build my own kernel is 2.6.33.4-95 which is newer than my original. Do you think it should matter? Because when i executed 'yumdownloader --source kernel' i got this version of kernel. Please let me know. Thanks, Satish.
