https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=232387 --- Comment #24 from [email protected] --- A commit references this bug: Author: luporl Date: Tue Jun 25 17:15:45 UTC 2019 New revision: 349377 URL: https://svnweb.freebsd.org/changeset/base/349377 Log: [PowerPC64] Don't mark module data as static Fixes panic when loading ipfw.ko and if_epair.ko built with modern compiler. Similar to arm64 and riscv, when using a modern compiler (!gcc4.2), code generated tries to access data in the wrong location, causing kernel panic (data storage interrupt trap) when loading if_epair and ipfw. Issue was reproduced with kernel/module compiled using gcc8 and clang8. It affects both ELFv1 and ELFv2 ABI environments.
