Hi,
I downloaded kernel 6.14.0 from kernel.org, applied the md patch and 
compiled it with the following procedure:

cd /usr/src
tar -xJf linux-6.14.tar.xz
ln -s linux-6.14 linux
cp /boot/config-6.1.0-32-amd64 /usr/src/linux/.config
cd linux
patch -p1 < ../md.patch
make -j12 bindeb-pkg
cd ..
dpkg -i *.deb

Then I started the testing. The only way to reproduce the problem for me 
is rebooting manually the PC until it manifest the kernel panic.

Test was on Z390-A + i7-8700k + 8 GB DDR with rootfs on 1 SSD M.2(SATA) 
and 1 SSD SATA 2.5

First I tried with the kernel on stable (6.1) and at the third reboot it 
panicked (I started with stable kernel to ensure that the panic 
occourred on that configuration before starting test with the patched 
kernel)

About the patched kernel, I run 50 manual reboot with some shutdown 
without any problem or kernel panic.

I don't know if this could be marked as fixed, maybe more test is needed.

In the next days I will perform some test on Z890-Z + Core Ultra 9 285k 
+ 32 GB DDR5 and report back results.

Hope that the patch could be backported to stable, backports kernel and 
testing (that is in freeze state).

For now it works. I will update you in the next few days.

Best regards.

Alessandro.
