What is different about 5.15 that keeps > this from working? This issue does reproduce for me locally but only with gcc-8 from TuxMake (i.e., a version from Debian), not with GCC 8.5.0 from kernel.org. $ git show -s --pretty=kernel 869807d760ee ("libbpf: Fix invalid return address register in s390") $ tuxmake -r podman -a powerpc -t gcc-8 -k allnoconfig default ... Inconsistent kallsyms data Try make KALLSYMS_EXTRA_PASS=1 as a workaround ... However, reverting the backport of 88b61e3bff93 ("Makefile.compiler: replace cc-ifversion with compiler-specific macros") does not resolve the issue for me: $ git revert --no-edit c8dad7eb1e6221e0363ee468dc46700bfbad6dd2 [detached HEAD 1669da6455e4] Revert "Makefile.compiler: replace cc-ifversion with compiler-specific macros" Date: Fri Dec 5 10:30:10 2025 -0700 13 files changed, 30 insertions(+), 37 deletions(-) $ tuxmake -r podman -a powerpc -t gcc-8 -k allnoconfig default ... Inconsistent kallsyms data Try make KALLSYMS_EXTRA_PASS=1 as a workaround ... My bisect landed on the backport of 19de03b312d6 ("block: make REQ_OP_ZONE_OPEN a write operation") and reverting that actually resolves the error. $ git bisect log # bad: [869807d760eeef0e0132eed3f1be6be16d084401] libbpf: Fix invalid return address register in s390 # good: [cc5ec87693063acebb60f587e8a019ba9b94ae0e] Linux 5.15.196 git bisect start '869807d760eeef0e0132eed3f1be6be16d084401' 'cc5ec87693063acebb60f587e8a019ba9b94ae0e' # bad: [ffd15ced026694355243064968a3b84269e0ee09] ARM: at91: pm: save and restore ACR during PLL disable/enable git bisect bad ffd15ced026694355243064968a3b84269e0ee09 # bad: [1ba52b54e5f45e982d61b4eeabbf28d78a5f9e75] drm/amdkfd: return -ENOTTY for unsupported IOCTLs git bisect bad 1ba52b54e5f45e982d61b4eeabbf28d78a5f9e75 # good: [8966a057d07281a5e65eaa3225cb072713921b25] Revert "docs/process/howto: Replace C89 with C11" git bisect good 8966a057d07281a5e65eaa3225cb072713921b25 # bad: [27df52e05f7dd606e18e869cb4f52ce1fbfe699f] tee: allow a driver to allocate a tee_device without a pool git bisect bad 27df52e05f7dd606e18e869cb4f52ce1fbfe699f # bad: [2b426fa49ef76bbe04671b3a861352b924a01b96] memstick: Add timeout to prevent indefinite waiting git bisect bad 2b426fa49ef76bbe04671b3a861352b924a01b96 # bad: [c126c39dc662661531c96acbbf5fc129ed7f535a] soc: qcom: smem: Fix endian-unaware access of num_entries git bisect bad c126c39dc662661531c96acbbf5fc129ed7f535a # good: [c142f0d16766ab7189af4b9128a2c81c56f7a01f] drm/sysfb: Do not dereference NULL pointer in plane reset git bisect good c142f0d16766ab7189af4b9128a2c81c56f7a01f # bad: [02dc541fc61c3e2dabc3574fe46a19f554ea5d8c] soc: aspeed: socinfo: Add AST27xx silicon IDs git bisect bad 02dc541fc61c3e2dabc3574fe46a19f554ea5d8c # bad: [23e0fecb7be5010e96b2948490799ef59ac4bea6] block: make REQ_OP_ZONE_OPEN a write operation git bisect bad 23e0fecb7be5010e96b2948490799ef59ac4bea6 # first bad commit: [23e0fecb7be5010e96b2948490799ef59ac4bea6] block: make REQ_OP_ZONE_OPEN a write operation $ git revert --no-edit 23e0fecb7be5010e96b2948490799ef59ac4bea6 [detached HEAD ddf3a34910b0] Revert "block: make REQ_OP_ZONE_OPEN a write operation" Date: Fri Dec 5 10:26:26 2025 -0700 1 file changed, 5 insertions(+), 5 deletions(-) $ tuxmake -r podman -a powerpc -t gcc-8 -k allnoconfig default ...
