My Fedora 33 test VMs stopped booting linux-next recently; reverting 81200b0265b1 "selinux: checkreqprot is deprecated, add some ssleep() discomfort" allows them to boot again. I'm guessing this warning wasn't intended to be quite *that* dramatic? --b. LSM: Security Framework initializing SELinux: Initializing. SELinux: CONFIG_SECURITY_SELINUX_CHECKREQPROT_VALUE is non-zero. This is deprecated and will be rejected in a future kernel release. SELinux: https://github.com/SELinuxProject/selinux-kernel/wiki/DEPRECATE-checkreqprot BUG: scheduling while atomic: swapper/0/0/0x00000002 no locks held by swapper/0/0.
