Hi Adrian,
[2] https://people.debian.org/~glaubitz/linux-image-6.12.38+1-sparc64-smp_6.12.38-1+sparc64_sparc64.deb
I've finally found some time to test those kernels on my Fire V215 (UltraSPARC III). Please excuse me if I missed something that's already been discussed. Unfortunately, none of the kernel packages in https://people.debian.org/~glaubitz/ and https://people.debian.org/~glaubitz/sparc64/ managed to boot my system. (I shortened the output for brevity, let me know if you need the full boot logs) linux-image-6.12.38+1-sparc64-smp_6.12.38-1+sparc64_sparc64.deb: [ 69.870700] crc32c_sparc64: sparc64 crc32c opcode not available.
