As another data point, I was running 4.15.0-106-generic on a BTRFS file server with an uptime since June. After rebooting Sept 4 to 4.15-0-115-generic, I've experienced this sort of deadlock every few days (on Sept 5, 8, and 10) under both the -115 and -117 kernels. So, given the above report on -112, it looks like a regression between -106 and -112. Hope that helps! (I'm going to give the HWE a spin, too.)
