Bad CPU speed after wake up ?

[ovof]

Hi all,

 

i've on a laptop, GM leo installer, upgraded to 10.5.2 with stock kext and kernel, thanks to EFI.

 

Everything works except two annoying thing :

 

1) sleep then wake up, the system works, but at a slow speed, like CPU or FSB has not been set to the corrected value.

 

2) i must set CPUS=1 at boot, or the system hangs randomly.

 

 

I tried Toh kernel 10.5.2. nothing better, even worse as it doesnt properly wake up.

 

 

Could you help me please ?

 

The worst thing i want to fix is the speed incorrect after sleep/wake.

 

THanks

 

BTW, its an NC6400 with T5500 centrino duo

For the first issue, bad speed after wake up,

 

i think its the fsb which is not corrected by the kernel or ACPI, or the CPU which as a bad clock.

 

I inject code, and havec seen that speedstep is enabled by default on my latop, i cant disable it in bios, and i'm running stock kernel with speedstep... It might be the issue. I'm trying right now to disable speedstep with wrmsr(MSR_IA32_MISC_ENABLE,l &= (1<<16),h )...

With CHUD utils installed I set Single CPU and I get chopy system, even the mouse pointer moves very slowly, if I boot with cpus=1 the system is slow but not tha chopy, weird

Yes same thing, choppy for one minute when disable all cores but one.

 

I injected code to disable speedstep on my laptop : reboot Perhaps i'm not in real mode where in injected the code ???
