Hi.

I have tried compile kernel with
http://tuxonice.nigelcunningham.com.au/downloads/all/tuxonice-for-linux-3.14.2-2014-04-28.patch.bz2
patch.
But it failed:
[***@hubbitus linux-3.14.2-200.hu.1.fc20.x86_64]$ LANG=C make -s
ARCH=x86_64 V=1 -j3 modules
ERROR: "function_trace_stop" [kernel/power/tuxonice_core.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
[***@hubbitus linux-3.14.2-200.hu.1.fc20.x86_64]$

I could do it only with next patch:

All modules compiled, kernel installed but I can't discover why it is
not work. You wiki (
https://github.com/NigelCunningham/Tuxonice-Userui/wiki ) absolutely
empty, documentation which present in aforementioned patch seams
outdated (only legacy pm-utils mentioned instead of systemd control).
Is there some documentation how start working with it and start
debugging what and why is not working?
