Bug ID: 977987
Summary: Kernel NULL pointer dereference crash from "t-daemon"
Classification: openSUSE
Product: openSUSE Tumbleweed
Version: Current

OS: Other
Status: NEW
Severity: Critical
Priority: P5 - None
Component: Kernel
Assignee: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx
Reporter: lmb@xxxxxxxx
QA Contact: qa-bugs@xxxxxxx
Found By: ---
Blocker: ---

The current tumbleweed kernel crashes for me on boot - it continues to
run, but the OS hangs in random places. Going back to 4.4.3 and system
is stable.

Kernel details:
kernel-default-4.5.0-3.3.x86_64
Source Timestamp: 2016-03-28 09:27:57 +0200

GIT Branch: stable
Distribution: openSUSE Factory
