The following actions will resolve these dependencies:

     Install the following packages:                             
1)     gcc-14-base:i386 [14.2.0-19 (testing, unstable)]          
2)     libc6:i386 [2.41-7 (testing, unstable)]                   
3)     libgcc-s1:i386 [14.2.0-19 (testing, unstable)]            
4)     nvidia-modprobe:i386 [570.133.07-1 (testing, unstable)]   

     Keep the following packages at their current version:       
5)     dkms [3.1.8-1 (now, testing)]                             
6)     firmware-nvidia-gsp [535.216.01-1~deb12u1 (now, stable)]  
7)     nvidia-kernel-common [20240109+1 (now, testing, unstable)]
8)     nvidia-kernel-dkms [535.216.01-1~deb12u1 (now, stable)]   
9)     nvidia-kernel-support [535.216.01-1~deb12u1 (now, stable)]

となってしまって nvidia ドライバでまた何かおかしくなったかなあ…とよくよく見てみると問題は dkms だった。 nvidia-kernel-dkms:ppc64el had to be dropped in 535.230.02 という修正が入っていて Breaks: nvidia-kernel-dkms (<< 535.230) となっていた。そうか dkms も APT Pinning しないといけなかったのか。以前の設定では確かに抜けていた。ということで dkms を追加した。

Package: libxnvctrl0 dkms
Pin: release c=main, n=bookworm
