[SOLVED] Laptop not booting since Kernel 4.17.2

smonsays · 2018-06-29 19:24:25

Since the update to linux 4.17.2 my Thinkpad 13 (Intel i5-6200U) freezes during startup. Interestingly, sometimes this does not happen and the laptop manages to boot. Furthermore, it boots just fine using the LTS kernel. During startup a lot of error messages appear and I am not exactly sure which of those are of importance, maybe it has something to do with this:

Additionally, I see some unusual "ucvideo 1-3:1.0: Entity type for entity Extension X was not initialized!" messages that might have something to do with the issue.

Has anybody an idea what might be causing the problem here?

You should try blacklisting the thinkpad_acpi module.

Not sure if related but have a look at this post,

Alright, after blacklisting thinkpad_acpi I can boot under the current kernel (4.17.2) as the problem was apparently related to this, thanks lo1! However, I do not fully understand what happened here: While unregistering the acpi battery hook something goes wrong as a hook is unregistered? Is this a bug that will be solved? Do I lose any relevant functionality by blacklisting thinkpad_acpi, i.e. with regards to power management?

Not sure why this happened, I just remembered this issue but loqs and seth were the ones who found this bug was related.

My guess is you don't need thinkpad_acpi at all (e.g. if the output from 'acpi -b' reports the correct battery status you're good to go).

Remember to mark your thread as SOLVED if that was all.
