We have bee using ZOTAC mini PC’s for awhile now and have been happy for the most part.
The one ongoing issue we have is rebooting. If they have been running for a few days they will hang at “Preparing for Reboot”
There is another post with this title:
Arne.F said, “Some J1900 boards has problems that it hang in bios at reboot. Try to add reboot=b or reboot=k to the kernel commandline in /etc/default/grub and regenerate the grub config.
grub-mkconfig -o /boot/grub/grub.cfg”
I can’t find any information about reboot=k or reboot=b. Does somebody have chapter and verse that explains this?
In my case I discovered this miniPC had a BIOS update which I applied. Now I wait a few days to see if that fixed it.
Where reboot_mode is one of warm (soft) or cold (hard) or gpio,
reboot_type is one of bios, acpi, kbd, triple, efi, or pci,
reboot_force is either force or not specified,
reboot_cpu is s[mp]#### with #### being the processor
to be used for rebooting.
