Merely a follow up.

I have tested this and run the change :

    therm_windtunnel: drop using attach_adapter

For weeks now with no issues.


I have never made those and never had a reason to. Sadly. Or maybe just sorry. I just download the kernel sources and do my own build and then install. There are no deb files anywhere.

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!

I'll have a look there myself.  See if I can make heads or tails out of

I guess I could figure out how to do that but it may be days of work.
A tar ball may work but then again ... who knows.

Guess I have to look at the "Debian way" to figure out the deb file

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

Almost always works well for me.

I’ll be happy to test it on my PowerMac7,3 G5 dual processor machine.

I have done that here for a month at least. On a G5 dual socket dual

I think there are actually four different models of the PowerMac G5s.

I gather you have the 4-core version.

Looks like just dual core. I don't think the IBM 970ppc was ever quad core.

I have access to each of the two different 2-core versions.

OKay so we have lots of that.

 Is there somebody out there with a single-core machine ...

I have that also.  Just have not powered it up in a while.

Feels like there is another step yet. The deb files.

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

One issue that I may have caused is that I generally build and test my
own tool path and thus I have separate readelf, gcc, autoconf and all the jazz that goes with it. I use those tools to build the kernels and have done so over and over for years. To be a "pure" Debian way then I would need to move all that stuff aside. Maybe.

I'll think on that.

I have 4.18.11 cooking right now and will follow up .. soonish.
