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

Replying to waddlesplash:

Thanks!

Summary: acpi_task 100% load of one of the CPU cores → Ideapad 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).

I have the same problem with HP Stream 11 laptop. So probably not a buggy firmware after all if the same happens with 2 different brands.

comment:11 by tqh, 5 years ago

Sorry, you only have the same symptoms. Lenovo needs its own driver to work. HP doesn't afaik. It should be tracked in its own bug. (Also HP is probably the buggiest of them all.)

Not likely. Lenovo needs a special driver. Acer should either be a different driver or a different problem.
