Hi,
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
interface.
I've tried putting them offline before suspending as well.
My test case:
Makefile:
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
%.x:
./hog
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.
My kernel:
Linux nixos 2.6.32.14 #1 SMP Sat May 29 22:06:43 UTC 2010 x86_64 GNU/Linux
using pm-utils-1.3.0
Any ideas or hints are appreciated.
