Title:
enabling ftrace on Hi1620 CS causes an Oops
Status in linux package in Ubuntu:
Confirmed
Bug description:
[Impact]
Attempting to enable the function tracer causes an Oops. This impacts the
current disco kernel, as well as latest upstream
(@5e7a8ca319268a70a6c7c3c1fde5bea38e1e5539).
This is 100% reproducible on D06 CS systems, but not reproducible on
D06 ES systems (the previous silicon rev).
[Test Case]
