Though through the Process Management Software (for me is Process Hacker 2), we can suspend such crazy thread in the "system" process (in my laptop, it is acpi.sys+0x1af7c), making PC runs smoothly but unstable, the faulty is that whole system is running without the problematic ACPI support -- which can cause many unsuspected problem from System Freeze to BSOD. Probably the final cause of this annoying problem is a defective BIOS file and thus the final solution is just to flash another "good" BIOS.
I have an ASUS N43sn Laptop with i5-2410 and GT 550M, and I only have the solution of such a model. For other brands, the problem is likely to be the BIOS, but I don't know what the exact solution is.So flash an old BIOS version from your manufacture's support site just at your own risks.
Here is my experience with my ASUS N43sn.
When I flashed the latest one (which on the support site is "BIOS 414" ) , the problem always appeared ,
but since I decided to flash the original one (which called "BIOS 205" ) , the problem has just gone , and everything runs smoothly.
"Rolling back" the BIOS must add something after the orignal command,
For ASUS with winflash software, just type "winflash /nodate" at the current WinFlash directory in the Command Prompt with Administrator Rights , choose the Ver.205 BIOS downloaded from ASUS's website. At least after that my laptop calmed down again from the CRAZY System Interrupts State!
Hope this will be helpful to everyone.
