From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Because you tried two different OSes and the point where it hangs is the point where the OS sends an APM/ACPI command to reboot / power off. This is the last thing the OS does. So if that's not happening something is wrong with the hardware, BIOS, or BIOS settings.
You could try the syslog (journalctl), but logging is probably already off at that point.
yeah journalctl logs show nothing relevant. I have disabled acpi and forced it(
acpi=force
), but that didn't fix this. There are a lot of different combinations of acpi settings I could try:But I found these from a guy which they didn't work on so I'm reluctant to try them.
did you check it /proc/cmdline if the params were taken into account? perhaps you edited the config but didn't update the initramfs
Yes, I've always made sure to use
update-grub
and checked cmdline to make sure it has the correct parameters. Regardless of acpi=force or acpi=off, it would still hang.And I guess if you're in front of the computer, you could just press the reset button or unplug it at that point (after it sucessfully synchronized the disks). no need to let it sit, there is no harm or data to be lost at that point.
that is what I end up doing right now, but if I'm on vacation and I need to reboot, I'm fucked.
