I am getting no output from echo 'w' > /proc/sysrq-trigger. Ls is hung
again so I can try any thing else you suggest to get data.

Good morning btrfs list,
I have been rsyncing files from an nfs mount to a btrfs filesystem.
After an rsync run I ls random subvols or directorys to check the
copy. About 60% to 70% of the time ls completely hangs. Ps aux
shows it as running but even when I let it go for up to an hour it
never finishes. Kill -9 will not stop the process. Dmesg shows
nothing beyond a successful mount at boot. I can't umount the
system because "filesystem is busy". I find that a forced reboot is
the only way to recapture the system. /var/log/messages has the
only indication (that I can find) that anything abnormal is
happening. A tail of the file is below. Thank you for any help and
advice.
Hit sysrq+w when this happens and give us all the tracebacks. Also which kernel
you are on would be helpful. Thanks,
Josef
