I'm very confused by this CI report, and I suspect that this may be a
bug in the i915 driver. The log above shows several instances of
messages like this:
<3> [414.085231] debugfs: File 'intel_wakeref@ffff88810f9c2308' in
directory 'ref_tracker' already present!
...but if you look at the patch, it changes the code to only call
ref_tracker_dir_init() when the "class" pointer isn't set. Since the
containing object is zalloced, that should ensure that it only does
this once:
if (!wf->debug.class)
ref_tracker_dir_init(&wf->debug,
INTEL_REFTRACK_DEAD_COUNT, "intel_wakeref");
I think that the only way this could be happening is if the driver is
doing something like zeroing out the object that contains the struct
ref_tracker_dir and reinitializing it.
Does the i915 driver do that? Can we make it call
ref_tracker_dir_exit() before doing so? I don't think that practice is
safe if there are outstanding references at the time it occurs.
