--- Comment #19 from Marta Löfstedt <marta.lofstedt at intel.com> ---
I file this here because I still believe we need to trim the ftrace buffer so
that we get "header" of the BUG_ON backtrace.
I this case I believe it is probably bug 102035. However, since we also have
bug 103533, I would need to objdump the actual kernel that was run in order to
figure out which line it was.
I don't know if decreasing the
CONFIG_GLOBAL_TRACE_BUF_SIZE further will help. Maybe the ftrace will always
write over the expected:
