Hi Ingo and Josh, for this cb8a2ef0848c commit, the bot has reported at [1] but with a different randconfig and a different issue pattern. And the bot didn't report new ones as it considered the bad commit was already reported. tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit: cb8a2ef0848ca80d67d6d56e2df757cfdf6b3355 LoongArch: Add ORC stack unwinder support config: loongarch-randconfig-002-20240812 (https://download.01.org/0day-ci/archive/20240812/202408120955.qls5oNQY-lkp@intel.com/config) WARNING: modpost: missing MODULE_DESCRIPTION() in net/ieee802154/6lowpan/ieee802154_6lowpan.o >> ERROR: modpost: "kvm_restore_lsx" [arch/loongarch/kvm/kvm.ko] undefined! >> ERROR: modpost: "kvm_restore_lasx" [arch/loongarch/kvm/kvm.ko] undefined! Later, there's fix at [2], but seems it doesn't solve all possible issues since the bot didn't report out explicitly.
