But that requirement is not documented. I'd be surprised to see that there is any documentation for that that BIOS SETUP option really does. But we can endeavor to find out, say by dumping the MSRs with default BIOS SETUP and with C-state disabled BIOS setup. My guess at this point is that this is a BIOS bug, or at least a BIOS quirk. please fetch the msr-tools from here: git clone git://git.kernel.org/pub/scm/utils/cpu/msr-tools/msr-tools.git and build rdmsr we can use it to dump out the MSRs with the BIOS defaults and compare the the same MSRs for the BIOS c-state disabled setting. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Increase Visibility of Your 3D Game App & Earn a Chance To Win $500!
