Title:
Bionic: Intermittently sent to Emergency Mode on boot with unhandled
kernel NULL pointer dereference at 0000000000000980
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Bionic:
Fix Released
Bug description:
===SRU Justification===
[Impact]
When TBT ICM firmware is not running properly, it may crash the kernel.
[Fix]
Protect against cases when ICM is not set.
[Test]
User confirmed the additional patch works.
[Regression Potential]
Low. It adds a simple logic to avoid NULL dereference.
===Original Bug Report===
Ubuntu Desktop 18.04 release version, running on a Lenovo T570 laptop.
Sometimes, at boot, the system goes into Emergency Mode. In looking
at journalctl -xb output, the following messages are logged:
