Mike: From your attachment, looks like you rebooted. So do this: echo 1 > /proc/sys/kernel/sysrq Reproduce the problem where you get blocked task messages in dmesg echo w > /proc/sysrq-trigger journalctl -k > kernel-sysrqw-btrfscleaner770blocked-2.txt Make sure you use the same mount options. Looks like you're using autodefrag, and inode_cache. Are there others? And can you say what the workload is? Especially because inode_cache is not a default mount option and isn't recommended except for certain workloads, but still I think it shouldn't hang. But that's a question for Liu Bo.
