The bug is “status: NEEDINFO”, so I assume it’s not fixed yet. In the meantime, manually loading the windfarm modules is a tested workaround.
Does this workaround work for you, too?
"However, there is a workaround: In addition to CONFIG_I2C_POWERMAC=y you
need to compile "Device Drivers → Macintosh device drivers → WINDFARM=y"
statically into the kernel. Then, the relevant WINDFARM_xx module gets
automatically loaded again."
Merely a follow up.
I have tested this and run the change :
therm_windtunnel: drop using attach_adapter
git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/macintosh?id=3e7bed52719de4b5b5fb900869e293eae0bc3f3e
For weeks now with no issues.
I am switching to 4.18.9 now and the drivers/macintosh/therm_windtunnel.c file therein is still original. I see no reason why
the change could not be pushed into the linux kernel proper.

Hi Dennis,
This is good news.
Seems to work.
If you can send me a way to download the .deb(s) for this kernel
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 guess I could figure out how to do that but it may be days of work.
A tarball may work but then again ... who knows.
Guess I have to look at the "Debian way" to figure out the deb file
issues.
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
core.
Thanks very much for all your work!
Feels like there is another step yet. The deb files.
Dennis
