Hi udippel, thanks for taking the time to send this bug report!
Unfortunately I'm gonna need more information to start looking into
this.
I'm assuming you're still able to boot despite those crashes, yes?
Please run the following command in order to collect the relevant system
logs + hardware info:
apport-collect 2080355
Thanks,
Vinicius
