Thanks! 1. Check what microcode version you have by running `grep microcode /proc/cpuinfo` 2. Extract the tarfile. 3. Install iucode-tool. 4. For each .bin file that was in the tarfile, run iucode-tool over it. For example, `sudo iucode-tool 2494656.bin`. You can pass multiple files at once to iucode-tool, so you could alternatively just run something like `sudo iucode-tool *.bin` 5. Check if your version of the microcode has changed with `grep microcode /proc/cpuinfo` 6. If your version of the microcode changed, then hopefully your issue is fixed. Make sure to re-run step 4 every time after you reboot, until your distribution's intel-microcode package is updated, or until you get a UEFI update. -- You are receiving this mail because: You are the assignee for the bug.
