I have CONFIG_SLUB_DEBUG and CONFIG_SLUB_DEBUG_ON enabled. I also have
various other debug options enabled, but slub debugging should be the
relevant one. I see the problem with several architectures.

- arm (all variants)
- arm64 (little and big endian)
- loongarch
- mips (all variants)
- nios2
- ppc (all variants)
- riscv (32 and 64 bit)
- x86 (32 and 64 bit)
