Title:
Falkor erratum 1041 needs workaround
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Zesty:
In Progress
Status in linux source package in Artful:

Bug description:
[Impact]
A hardware issue can lead to a kernel crash or unexpected behavior.
[Test Case]
The issue presents itself most commonly as a boot-time crash. It doesn't
effect all Falkor CPUs, and only rarely occurs on CPUs that are effected.
[Regression Risk]
The fix is entirely in arm64 code, mitigating the risk to other
architectures. The biggest regression risk is performance, as the workaround
involves adding an instruction barrier prior to disabling the MMU.
