[1.] One line summary of the problem:
[HP Pavilion 360 - 13-a200nt (ENERGY STAR)] Kernel parameter acpi_osi=
required to boot
[2.] Full description of the problem/report:
When booting my HP Pavilion 360 - 13-a200nt (ENERGY STAR), it stops with
just blank (black) screen and the Caps Lock doesn't respond when pressed
stating machine doesn't respond to any input at all. If you add
"acpi_osi=" to kernel parameters, it boots fine with entire ACPI
functionality seems to be working.
