It has been reported that under certain circumstances, it may be possible for local users to crash dual-boot systems. This issue is present due to the BIOS failing to reset certain Model-Specific Registers (MSRs) on reboot. This could leave the CPU in a potentially unstable state, in the event that SYSENTER is invoked by an operating system that does not support the instruction.
