Confirmed. Bisection says 873d50d58f67ef15d2777b5e7f7a5268bb1fbae2 is the first bad commit commit 873d50d58f67ef15d2777b5e7f7a5268bb1fbae2 Author: Kees Cook <[email protected]> Date: Mon Jun 17 21:55:02 2019 -0700 x86/asm: Pin sensitive CR4 bits this is on a bog-standard Intel setup with F30, both desktop and laptop (i9-9900k and i7-8565u respectively). I haven't confirmed yet whether reverting just that one commit is required, or if I need to revert the cr0 one too. I also don't have any logs, because the boot never gets far enough. I assume that there was a problem bringing up a non-boot CPU, and the eventual hang ends up being due to that. Linus
