Laptop runs slow until after suspend/resume

view story

https://bbs.archlinux.org – Ever since the update kernel 3.4 my laptop runs slow until after a suspend/resume.It seems something has gone wrong with the power management settings from powerup, that then get corrected through the suspend/resume cycle.Its now getting rather anoying having to suspend my machine after boot, just to be able to use it.Does any know what the problem might be or what information I should look at to help identify it.Here is some info on my machine:HP Compaq 6715b, AMD Turion64 X2, ATI RS690M [Radeon X1200 Series] (Actually X1300)Linux tigger 3.4.5-1-ARCH #1 SMP PREEMPT Mon Jul 16 21:35:54 CEST 20 (HowTos)
