Ok, the offending commit is actually 177cf92de4aa97ec1435987e91696ed8b5023130,
at least that one matches the diff of your change. It references the other
commit, but that's not the commit itself.

For debugging it might be useful to do the suspend partially. You can disable
certain parts of suspend (it will immediately resume if you do this)

# echo <mode> > /sys/power/pm_test

See

# cat /sys/power/pm_test

for a list of all possible values. If you manage to reproduce the bug with this
please attach the drm.debug=0xe dmesg.
