Created attachment 256855 [details] boot.log Kernels 4.11+ reset BIOS settings on Thinkpad Yoga Description of problem: After installing Linux 4.11, my BIOS settings get reset on every restart. Booting the system after it was run with kernel-4.11.3-200.fc25.x86_64 shows a BIOS message "Configuration was reset", the system restarts and all settings are reset to default. This doesn't happen with the 4.10 kernels. Version-Release number of selected component (if applicable): * kernel-4.10.17-200.fc25.x86_64 * kernel-4.11.2-200.vanilla.knurd.1.fc25.x86_64 * kernel-4.11.3-200.fc25.x86_64 * kernel-4.12.0-0.rc2.git0.1.vanilla.knurd.1.fc25.x86_64 How reproducible: always Steps to Reproduce: 1. Install kernel-4.11 or 4.12-rc2 2. Boot into it 3. Restart the system 4. "Configuration was reset" BIOS message is shown 5. The system resets 6. BIOS settings are back to default 7. Change some BIOS settings 8. Boot with an older kernel (<=4.10), and reboot 9. BIOS settings stay as set Actual results: see above Expected results: The system restarts without resetting BIOS settings Additional info: * Thinkpad S1 Yoga (Type 20CD) * Tested BIOS versions 1.29 and 1.31 (latest)
