no poweroff on reboot or shutdown

My system recently picked up a bug where it won't poweroff when I issue either "reboot" or "shutdown -h now". In both cases, it goes through the normal shutdown steps, but halts without an error message at the power-off stage. This sounds nearly identical to this thread:

https://unix.stackexchange.com/questions/264189/computer-doesnt-power-off-at-shutdown-reboot-arch

But their solution, adding "acpi=force" to GRUB_COMMAND_LINE_DEFAULT didn't work for me.

Unfortunately, I don't reboot that often, so I'm not sure when this first started, except that it was in the past few months, so it's hard to say when update(s) might have caused it.

Any ideas?

I also tried setting "acpi=off" in grub. To me, this seems counter intuitive, but I wanted to see what would happen. This had no effect on this issue, and the only change I can see is that the system isn't able to set the hardware clock at boot.

I also looked through the bio settings, and couldn't find anything that seemed related.

One other note: this system is dual-booted with windows, and, although I mostly just use linux, yesterday I had to boot into windows. Windows was able to poweroff without issues, so I doubt that it's a hardware problem.

I recently faced similar issue after system update. For me, it was

When I upgraded to sys-apps/sysvinit-3.08 I received this elog message:

Just add one line in ~/.bashrc and carry on as normal

Although the timing is unfortunate, it looks to me like OP's problem has nothing to do with the bug fix in sys-apps/sysvinit. OP specifically stated that he tried using the pre-fix version, and it did not help. Additionally, he has tried the elaborated invocation that is supposed to work in the post-fix version, and it does not help. I have used shutdown -h now successfully, and the system powered off, when using =sys-apps/sysvinit-3.08, a version which supposedly requires you to "do it right." Based on all this, I think OPs' problem is not in with the bug fix in sys-apps/sysvinit. Instead, this is some other problem. OP: if you increase the kernel's output verbosity, do the final lines left on screen provide anything useful? Does the sysrq that forces an immediate poweroff (without syncing, so you must save your data first!) turn off power in the bad case? Based on your kernel upgrade history, is there a last known good / first known bad kernel?
