[Letux-kernel] suspend issues letux-4.15-rc8

[Andreas Kemnade]

Hi,

I have run my suspend test script, and it shows trouble:

no modules: cur: 60868 delta: 60868
+w2sg0004 cur: 60868 delta: 0

-> 60mA idle -> ok

before: 830192
after: 827878
average 27860 uA over 299 seconds

-> 27mA suspend -> nearly ok,

-> too high (pm_runtime_suspend of phy/musb is not doing its job/reference counter
   unbalanced, ...)
   was also better at some time with 4.x

average 53578 uA over 299 seconds

-> too high (pm_runtime_suspend of phy/musb is not doing its job...)

+ifup cur: 90321 delta: 179

-> also  too high.

Conclusion: run this script more often
to find issues earlier. I hope that can be automated. I almost have all
ingredients for automating that.
