If I were to send you some test patches, could you create a kernel with them

Doubtful.
Sardonimous,
OK, that essentially eliminates getting DMA to work. The cost of a
MacBookPro7 is too much for me to acquire one to debug that issue.
On my PowerBook G4, I also got the failure to connect, thus I should be able
to fix that problem, but getting a new kernel with the fix onto your machine
will not be easy.
It might be possible to follow the arch instructions for patching the kernel
https://wiki.archlinux.org/title/Kernel/Arch_build_system
It takes about a day to rebuild the kernel following this procedure.
Is it possible to ssh into your machine, or to use TeamViewer? Those questions
do not need an answer now, but think about them.
This is complicated by being in a CGNAT environment. I usually do this via
tailscale. Will have to think about it.

Should pio=1 qos=0 cause the problems that it does? It if is no longer a
supported configuration, perhaps it should fail more gracefully.
Sardonimous,
Sorry that it took so long to get back to you.
For my ppc32, there is no regression. It took a while to learn the pio=1 and
qos=0 are BOTH needed. That I do not understand, but with both set, the device
works with kernel 6.4 and all earlier kernels that I tried. Fortunately, I did
not need to do the entire bisection.
I am working on eliminating the warning that appears with qos=0, but it does not
inhibit operations.
@Bagas Sanjaya: Please mark this "regression" as invalid.
