I have these patches in addition to current git:

That is all I get. Is that what you mean?
Related to that this morning at home (not university!) I had the hanging
again, had to remove the module. Always after wake up from ram (s2ram).
There I had in the log:

stuck for 10000 ms.

But somehow it didn't actually start working again.
Best wishes
