I encountered this issue installing xubuntu™ 18.04-LTS on an emachines®/acer® EL1210-09 (2.3 GHz Advanced Micro Devices® Athlon® LE-1620; nVIDIA® nFORCE® 720 chipset; 2 x 2 GiB DDR2 main memory) with a Shuttle® PSU upgrade (PC6300001 in for stock 220W LITEON®) and the planar C77 geForce® 64-bit GPU by-passed for the nVIDIA® GF-109 on an msi® N610GT-MD1GD3/LP half-height video display adapter. I normally use:
GRUB_CMDLINE_LINUX_DEFAULT="debug"
in /etc/default/grub, which is how I confirmed the issue: Depending on shutdown or reboot option, the system halts at "Starting reboot..." or "Starting power-off...", forcing a manual power-down. Additionally:
GRUB_CMDLINE_LINUX_DEFAULT="debug acpi=force"
had no effect, and:
GRUB_CMDLINE_LINUX_DEFAULT="debug acpi=off"
only got me to a timestamped "reboot:System halted". Will report back after checking effect of nVIDIA® geForce® driver package for C77 GPU (part of nF720 chipset).
