After a lots of private mail traffic and debuggin efforts with Ingo, yester= day=20 i simply requested to ignore that problem (at least until i can reproduce=20 same with different machines).=20 Yesterday i turn back to vanilla 2.6.18.8 to see the situation with it and = i=20 reproduce the problem even with lower loads. Seems like this piece of hardware is dieing [For a while my laptop starts t= o=20 poweroff suddenly without any log/error etc] and i think all these problems= =20 caused by this. Or at least/ for me/ this laptop (sony vaio fs-215b) is not= a=20 stable test bed for this kind of human involved testings. Ingo cannot reproduce same audio/video out-of-sync problems with his setups= ,=20 and currently i'm the only person deals with that problem.=20 And for some boots kernel reports wrong frequency for my cpu (and notice th= e=20 timing difference), [this maybe a overheat problem but aslo i'll try=20 disabling CONFIG_NO_HZ as Ingo suggested] =2E..
