I applied it and built. Although I am pretty sure, that the patch is included
in the built kernel, Is there an easy way to validate that the patch is really

This kind of output I do not see in the syslog anymore during regular
operation now (is that the 10-second polling?):

> Let me know if it actually helps your suspend/resume issues.
So far the patch at least did not break anything visible to me :-) Since I
cannot reproduce the suspend/resume issues reliably, this takes now some time.
If I will have not seen it within the next two weeks, the problem is fixed or
at least improved.
Many thanks,
Rainer
