Is this UP?
There's the fast_tlb race that Peter fixed in commit 29eb77825cc7 ("arch, mm: Remove tlb_fast_mode()"). I'm not seeing how it would cause infinite TLB faults, but it definitely causes potentially incoherent TLB contents. And afaik it only happens with CONFIG_PREEMPT, and on UP systems. Which sounds like it might match your setup...
