Hm, dunno what all is in that kernel. Huge swapout with yum upgrade shouldn't be happening I don't think, upgrades here certainly don't (I'm using suses upgrade dohickey though...). I can only recommend trying latest/greatest stock kernel.

Yes, that's the symptom I was refering to. If you see that under reasonable CPU load, and _without_ major swapping going on, then I'd be suspicious of scheduler trouble. Swap can definitely keep X off the cpu for extended periods, and that seems to be what triggers the repeated keys behavior. (I've never troubleshot it, so must say _seems_)
