Hi Tom, Yes, we are missing some HMM fixes/changes from 5.1, but the crash log seems not related to those fixes/changes in 5.1. I did see the similar crash log in __mmu_notifier_release path that should be fixed by the patch "use reference counting for HMM struct" as Alex mentioned. Since you have applied that patch, this could be another new issue. May you provide steps how to reproduce the issue while running piglit?
