--- Comment #2 from Antonio Chirizzi antonio.chirizzi@gmail.com --- Hello Michel,
I have installed the latest stable ubuntu kernel after my laptop froze again half an hour ago (but still accessible through ssh).
# uname -a Linux antonioRyzen 4.18.0-041800-generic #201808122131 SMP Sun Aug 12 21:33:20 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
With this one at least no call trace are being shown in the log.
I'll let you know if it freezes again.
Thanks!
