it is really rare to see a system running with acpi=off. May I know why acpi=off is used in the first place?
for this particular issue, please confirm if problem still exists with acpi_osi=!. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1848445 Title: [HP Pavilion 360 - 13-a200nt (ENERGY STAR)] Kernel parameter acpi_osi= required to boot Status in Linux: Incomplete Status in linux package in Ubuntu: Triaged Bug description: When booting my HP Pavilion 360 - 13-a200nt (ENERGY STAR), it stops with just a non-blinking white cursor on screen in the top left, and the Caps Lock doesn't respond when pressed.
