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...
