I just updated to kernel 4.5 in [testing] and twice in a
row, the boot failed with a CPU hang reported at different
times. At some point the NMI watchdog kicked in. I had to
hard reboot the system. I currently don't have the time to
debug this and just want to leave a warning here.
CPU: AMD E-2000 with integrated Radeon HD 7340. System: Lenovo ThinkPad Edge E135 |
This task depends upon
edit: I even tried installing linux-lts which went fine. But when trying to boot it, a message about missing modules from 4.5 is printed, the system does not find the root disk by its usual UUID and I get dropped to a shell. This shell is useless and I managed to hang the system several times with some commands. Mkinitcpio seemed to do its job with the LTS kernel. I have no idea what's going on. I never had any problems downgrading a kernel before.
edit2: Okay, after I stopped being an idiot, I managed to get linux-lts working after all.
Long story short, my issue is the following:
https://bugzilla.kernel.org/show_bug.cgi?id=114201
It can be "fixed" by blacklisting sp5100_tco. This allows my system to boot without issues.
4.6-1 is now in testing, is the issue still present?
No issues on my core i5 6600 by the way.
