* is it safe to run snapshots, btrfs send/receive when doing a scrub?

I've started a scrub on a btrfs filesystem, then did btrfs send/receive
a couple of gigabytes, made a few snapshots... Something strange
happened to the filesystem.
rsync processes I run are hanging, "sync" never returns. Simple writes
like "date > testfile.txt" work fine.
I've canceled the scrub, but the filesystem didn't "recover".
dmesg showed this:
