Hi Catalin,
The original bisection is for "BUG:kernel_hang_in_early-boot_stage" which locate to commit c566586818, and the boot will go on and meet the error "RIP: 0010:clear_page_orig+0x12/0x40" if we set CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE=400, but the error shouldn't cause by commit c566586818 because we can reproduce the error on parent commit.
Best Regards, Rong Chen
