Thanks a lot for guidance!
yeah, we reached back to until v5.14-rc1 which still has similar issue, and v5.13 is clean. new bisection was triggered then we got '7118fc2906'
this was already reported as "[linus:master] [hugetlb] 7118fc2906: kernel_BUG_at_lib/list_debug.c" at https://lore.kernel.org/all/202301170941.49728982-oliver.sang@intel.com/ and I add you, Hyeonggon, Feng and Fengwei there.
hope that would be helpful.
