Hi,

I'm starting to wonder if it's not related to
46517008e1168dc926cf2c47d529efc07eca85c0 "ipv4: Kill
ip_rt_frag_needed()."

Cheers,

Hmm, most probably problem came with commit
ceb3320610d6f15ff20dd4c042b36473d77de76f
(ipv4: Kill routes during PMTU/redirect updates.)

Following patch should help :
