Still the same issue with 5.13.15.
diff -r --no-dereference /gnu/store/y9r7physjpa23znb7r6rg38wpmxrkp0s-linux-libre-5.13.15{,-check}
Binary files /gnu/store/y9r7physjpa23znb7r6rg38wpmxrkp0s-linux-libre-5.13.15/bzImage and /gnu/store/y9r7physjpa23znb7r6rg38wpmxrkp0s-linux-libre-5.13.15-check/bzImage differ
All the best,
