Hi Michael,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: cd796ed3345030aa1bb332fe5c793b3dddaf56e7
commit: e02152ba2810f7c88cb54e71cda096268dfa9241 powerpc: Drop -me200 addition to build flags
date: 3 weeks ago
config: powerpc64-randconfig-r025-20201208 (attached as .config)
