Description of problem:
When I try to boot the system with kernel 2.6.40, the following appears.

My CPU is an AMD Turion X2 Trinidad. It runs perfectly Linux 2.6.38.
Version-Release number of selected component (if applicable):
Boot the system with the new kernel and an AMD Turion X2 Trinidad CPU. You won't get too far.
System hangs. When I try to reboot, kernel segfaults, so, I can't even reboot.
System working as usual.
*** This bug has been marked as a duplicate of bug 690930 ***
Although the issue is the same, this can't be really a duplicate of bug 690930, since the former is filed against Rawhide. This bug is filed against Fedora 15, and it demands attention and a quick fix.
Installing microcode_ctl-1.17-17.fc16.x86_64.rpm over my Fedora 15 system makes the system bootable again and fixes the issue (for now). Please, pull that package to the F15 tree ASAP.
microcode_Ctl 1:1.17-17.fc15 is in updates now.
