[Pm-utils] cores offline after pm-suspend?

Some weeks ago I got a new laptop running core -i5 processsor.
Everything seems to be working. However after resuming from suspend to
ram htop only shows one core having 100% utilization and I can't seem to
fix this putting cores off and online again using the sys cpuX/online
I've tried putting them offline before suspending as well.
My test case:
a4: a1.x a2.x a3.x a4.x
all: a1.x a2.x a3.x a4.x a5.x a6.x a7.x a8.x a9.x a10.x a11.x b1.x b2.x b3.x b4.x
hog is a just a c prog running a dummy loop which lasts about 4 secs.
I made a screenshot of htop:
Make started 4 processes, however only one is running on a core.
make -j4 doesn't finish faster than make -j1 either.
Do you have any idea how to start debugging this issue?
Of course everything is fine after rebooting.
Linux nixos 22.214.171.124 #1 SMP Sat May 29 22:06:43 UTC 2010 x86_64 GNU/Linux
Any ideas or hints are appreciated.
