There is an error "kernel panic" when moving to the kernel 4.18.6 and above. Kernel "4.17.10" works stably. On another machine, the kernel 4.18.6 is stable. Perhaps the problem is in incompatibility between the kernel and the processor. Previously, there was no such error. Reproducible: Always Steps to Reproduce: 1. Install package gentoo-sources-4.18.6 and above. 2 The new kernel is configured with the command "make oldconfig" 3. Build and install new kernel 4. Boot the system with a new kernel In the error log "kernel panic" there are lines: -------------------------------------------------------------------------- Kernel panic - not syncing: Attempted to kill init! exit code=0x00000007 sched: Unexpected reschedule of offline CPU#0 -------------------------------------------------------------------------- Disabling the "CONFIG_SCHED_SMT" and "CONFIG_SCHED_MC" options in the kernel does not solve the problem.

Why do you think this is a bug on gentoo and not in the kernel (upstream)?
I installed the kernel using the package "sys-kernel/gentoo-sources-4.18.6", not the image from the site "https://www.kernel.org/". I agree with Jonas Stein that most likely is a kernel bug
With the kernel 4.17.19 from the sys-kernel/gentoo-sources-4.17.19 package everything works without errors. The error is most likely in the kernel version 4.18
Hi, Andrew. Can you test 4.18.17? If that fails, would you be willing to do a git bisect between the latest working on and the failing kernel?
I have already switched to kernel 4.19. Everything works without errors. Problem solved
Good news
