I've discovered an issue in the kernel which is causing sleepgraph
(analyse_suspend) to hang the system when it tries to get a callgraph
trace over suspend/resume. It happens on kernels 4.15.0-rc1 and newer.
I've whittled it down to 3 items which have to be set for the hang to
occur:
1) enable fu

Early trace callgraphs can be extremely large on systems with
several seconds of boot time. The max_depth parameter limits how
deep the graph trace goes and reduces the output size. This
parameter is the same as the max_graph_depth file in debugfs.

I've been using early boot trace to gather callgraph data on filtered
functions but something appears to have broken it in v10.0. The graph
trace worked fine in v4.10-rc8, so something changed since the release.
Issue:
