Verify your computer has more than 200 MB available If your computer is running low on hard drive space, your Windows swap file will be unable to increase in size when needed. This situation can cause programs to be swapped between memory and the hard drive more frequently, which can lead to more GPFs. http://www.computerhope.com/issues/ch000224.htm Determining available hard drive space. Recently installed software or hardware If you have recently installed new software or hardware uninstall or reinstall that software or hardware to verify it is not causing your issue. Uninstalling Windows software. Disable external cache If your CPU utilizes external cache disable it temporarily to verify if it is causing your GPF error messages. If this option is available it can be disabled through CMOS Setup. If this resolves your issue it is recommended that you contact the manufacturer of your computer, motherboard manufacturer, or CPU manufacturer for additional recommendations. Tip: In some cases a BIOS update designed for this problem can also resolve cache related issues. Disable Power Management and screen savers If you are receiving GPFs when the computer is inactive for extended periods, disable Power Management and screen savers to ensure that they are not causing your issue.

An attempt to violate this rule results in a general-protection exception (#GP). more on that(http://www.lpthe.jussieu.fr/~talon/pentium3.pdf) Inside the kernel each exception is handled by a specific exception handler, which usually sends a Unix signal to the process that caused the exception. In our case : the kernel will generate a signal SIGSEV. The exception handler in this case is general_protection( ) (https://github.com/torvalds/linux/blob/master/arch/x86/include/asm/traps.h) EDIT : in this link you can get a great explanation about how the kernel compare DPL, CPL and RPL: http://duartes.org/gustavo/blog/post/cpu-rings-privilege-and-protection Another good link: http://www.logix.cz/michal/doc/i386/chp06-03.htm share|improve this answer edited Aug 18 '12 at 8:45 answered Aug 16 '12 at 10:30 TOC 3,185815 thank, but how to compare CPL and DPL? and where is reality code in kernel source of linux? –Nguyễn Vỹ Aug 17 '12 at 8:18 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up
