I am seeing this bug on a ubuntu 16.04 box running on proxmox 5.1. Running 4.4.0-72-generic x86_64 guest (linux-image-4.4.0-72-generic).
Under heavy I/O sometimes the guest get stuck for couple of seconds and this error is printed: [538796.529342] hrtimer: interrupt took 37764682 ns
After that the guest becames unbearably slow and only reboot helps.
