dmesg output just loaded system (Gentoo)

I got problem with Intel X25-M SATA SSD (SSDSA2MJ080G2C1) drive, it making system runs slow after resuming from idle period. When system just booted everything normal, but if leave PC idle for around 20 mins and then use it again- gnome interface and video playing becomes slow.

  CPU load become very high - X root especially

And this is live-time shooting http://www.youtube.com/watch?v=cNQEnMvtH0k

 My primary system is Gentoo Linux amd64 installed on SSD. 
And just for test i have installed Ubuntu 11.04 to separate ordinary not SSD harddrive then left PC idle for night then tested video playing and gnome interface- everything was ok.
But when I mounted SSD partion - all become slow.
And dmesg showed this one:
