SubjectRe: [BUG] 2.5.65: Caching MSR_IA32_SYSENTER_CS kills dosemu

OK, running dosemu at the console does not cause a lock up. More
specifically: just running dosemu doesn't cause a lock up ever. To get
it to lock up, I have to run this game I play. Under X, just running the
game and waiting at the game's main menu causes the lock up in a couple
minutes. At the console, the game's graphics mode is not supported, so I
get a blank screen. But if I run the game blind and wait at the main
menu, there is never a lock up.

Also, it seems that turning off preempt makes the problem go away. At
least, I haven't got any lockups yet.

Cheers, Wayne
