I am encountering the dirlist hanging issue on multiple clients and none of them are Ubuntu.
Debian buster running kernel 4.19.0-2-amd64. This one was working fine until after ceph was upgraded to nautilus
Proxmox running kernels 5.0.21-1-pve and 5.0.18-1-pve

Ubuntu's 4.15.0-66 has this bug, yes. -65 is safe and -67 will have the fix.
