The "fs_mount: mount() succeeded but ops is NULL!" panic in the second syslog was probably fixed in hrev52690.

Summary: acpi_task 100% load of one of the CPU coresIdeapad need special driver: acpi_task 100% load of one of the CPU cores

Did it work with older Haiku versions? It seems likely Ideapads need special drivers for hotkeys and fans and so on, so it looks like a poor fit for Haiku until a developer with that hardware writes a driver.

Even if it does, why would that cause acpi_task to have 100% CPU usage?

If it needs a special driver to respond and clear the notification. What I could tell is 'input buffer full' was an error on other OS.

Also make sure to upgrade to latest firmware as Lenovo has updated the Embedded Controller Firmware (meaning it was buggy before).
