Kernel panic on MSI Wind / Intel Atom #7

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Any write to kern.cputhrottle_curfreq produces kernel panic (grayed screen). 

My system: MSI Wind Netbook (Atom 270), Leo 10.5.0 (original) + Combo upto 
10.5.4 + 
Chameleon 1.0.11 + SMBIOSResolver.kext + Natit.kext + RealtekR1000 1.04

----------------
Loaded in single user mode kext said that it can't get Pstate table from ACPI. 
`sysctl -a | grep 
throttle` output nothing.
Before panic in NORMAL mode `sysctl -a|grep throttle` outputs this:

Hi, could you edit the Info.plist file inside the kext and set KernelFeatures 
to 0 or 3, and then try again? Please 
ask for help on the forum if you are not sure how to do that.

I tried different values from 0 to 3 for KernelFeatures and results were same.
I can't say exactly if I tried all of the values, but I believe that I did.
Sorry, I can not check it because my Wind is now reverted back to WinXP.

Changing to WontFix because user cannot test anymore.
