Research direction
Start by reproducing the reported make modules -j$(nproc) build on Ubuntu 25.04 with Linux 6.19.8 and NVIDIA modules 595.58.03, then inspect the attached build.log for the objtool errors involving MITIGATION_RETHUNK and naked returns. Done means identifying the affected source or compatibility boundary and confirming a build that no longer fails.
