Is it supposed to work on x86_64?

I've tried enabling something minimal (full config attached):

CONFIG_PROVE_SPIN_LOCKING=y
# CONFIG_PROVE_RW_LOCKING is not set
# CONFIG_PROVE_MUTEX_LOCKING is not set
# CONFIG_PROVE_RWSEM_LOCKING is not set
CONFIG_LOCKDEP=y
CONFIG_DEBUG_LOCKDEP=y
CONFIG_TRACE_IRQFLAGS=y
# CONFIG_DEBUG_SPINLOCK_SLEEP is not set
CONFIG_DEBUG_LOCKING_API_SELFTESTS=y
# CONFIG_DEBUG_KOBJECT is not set
# CONFIG_DEBUG_INFO is not set
# CONFIG_PAGE_OWNER is not set
# CONFIG_DEBUG_FS is not set
# CONFIG_DEBUG_VM is not set
CONFIG_FRAME_POINTER=y
# CONFIG_UNWIND_INFO is not set
CONFIG_FORCED_INLINING=y

---

and I get unexpected failures in the validator self test, and then a
kernel panic. Something like this:

[test output]
