You are right, I'm using Intel Core 2 Duo processor with DP965LT board that is
capable of VT extensions. However, I'm using vanilla 2.6.18 kernel in X86_64,
no additional patches, nor XEN or VMWARE is running (even their modules are
not loaded). Moreover, SYSRQ-B (emergency reboot) works fine. System graceful
reboot does not work.
