II just tried to install debian on a ultra sparc III based Sun Ultra 45 workstation with the newest netinst image I could find, but the resulting install is not able to mount the root filesystem to complete the boot process.
The UltraSparc IIIi cpu in this machine lacks the crc32 opcodes and needs to use the crc32c_generic driver instead. Is this expected behavior because the machine is too old, or is this a bug?
