Re: PowerMac G5 fans run out of control with kernel 4.17.0-3-powerpc64 but not with 4.16.0-1-powerpc64

Thanks for the reply, Dennis!

I tried following the instructions at 
but the build process errored out before it managed to build a kernel.  Would you be willing to coach me through the process?  I’ll start with re-trying what I did and send you the logs with the error messages.  If you can spare the time to look at the logs and suggest what I’m doing wrong, I’d be very grateful!

Maybe by working together we can figure it out between us…

I think there are actually four different models of the PowerMac G5s.  Single socket single core (1 core total); Single socket dual core (2 cores total); Dual socket single core (2 cores total spread over two sockets); and Dual socket dual core (4 cores total).  I gather you have the 4-core version.  I have access to each of the two different 2-core versions.  Is there somebody out there with a single-core machine that would be willing to test it if Dennis and I can build a kernel “.deb”?

There’s *always* more work to do.  That’s a given!  (-;
