The kernel was built using defconfig with the additional config fragment from: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/selftests/mm/config This works fine on v6.15-rc7. A bisect identified this patch as introducing the failure. Bisected it on the tag "v6.15-rc7-7-g4a95bc121ccd" at repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git Failure log: 11193 03:29:14.806502 # # running ./migration 11194 03:29:14.806876 # # ------------------- 11195 03:29:14.820939 # # TAP version 13 11196 03:29:14.821236 # # 1..6 11197 03:29:14.821519 # # # Starting 6 tests from 1 test cases. 11198 03:29:14.821773 # # # RUN migration.private_anon ... 11199 03:29:34.602964 # # # OK migration.private_anon 11200 03:29:34.603418 # # ok 1 migration.private_anon 11201 03:29:34.603687 # # # RUN migration.shared_anon ... 11202 03:29:34.973479 # # Didn't migrate 1 pages 11203 03:29:34.973855 # # # migration.c:175:shared_anon:Expected migrate(ptr, self->n1, self->n2) (-2) == 0 (0) 11204 03:29:34.984787 # # # shared_anon: Test terminated by assertion 11205 03:29:34.985105 # # # FAIL migration.shared_anon 11206 03:29:34.985365 # # not ok 2 migration.shared_anon 11207 03:29:34.988568 # # # RUN migration.private_anon_thp ... 11208 03:29:54.597572 # # # OK migration.private_anon_thp 11209 03:29:54.597951 # # ok 3 migration.private_anon_thp 11210 03:29:54.598487 # # # RUN migration.shared_anon_thp ... 11211 03:29:55.011183 # # Didn't migrate 1 pages 11212 03:29:55.011524 # # # migration.c:241:shared_anon_thp:Expected migrate(ptr, self->n1, self->n2) (-2) == 0 (0) 11213 03:29:55.022519 # # # shared_anon_thp: Test terminated by assertion 11214 03:29:55.022834 # # # FAIL migration.shared_anon_thp 11215 03:29:55.027864 # # not ok 4 migration.shared_anon_thp 11216 03:29:55.028156 # # # RUN migration.private_anon_htlb ... 11217 03:30:14.595327 # # # OK migration.private_anon_htlb 11218 03:30:14.595777 # # ok 5 migration.private_anon_htlb 11219 03:30:14.596398 # # # RUN migration.shared_anon_htlb ... 11220 03:30:34.595239 # # # OK migration.shared_anon_htlb 11221 03:30:34.595623 # # ok 6 migration.shared_anon_htlb 11222 03:30:34.595859 # # # FAILED: 4 / 6 tests passed. 11223 03:30:34.603816 # # # Totals: pass:4 fail:2 xfail:0 xpass:0 skip:0 error:0 11224 03:30:34.604110 # # [FAIL] 11225 03:30:34.604342 # not ok 55 migration # exit=1 Thanks, Aishwarya
