I confirm I'm having this problem too since migrating to Bionic from Xenial. My setup is a bit analogous to the original bug reporter: I have 5 drives (22 TB) in RAID1, organized in around 10 subvolumes with up to 20 snapshots per subvolume. After some hours running normally, at some point

This issue appears to be an upstream bug, since the bug still exists in mainline without a revert. Would it be possible for you to open an upstream bug report[0] and maybe ping the patch author? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution

I tried to build a Bionic test kernel with commit fb235dc reverted, but it does not revert cleanly and requires a back port. Do you have the back port you performed and can post to the bug? Also, would it be possible for you to test the latest mainline kernel to see if the bug is already fixed
