Feel free to snip.
As the involved tree block is not shown anywhere.

So it's not any root node corrupted.
It may be some extent tree node corrupted in this case.

While to inspect it, we need some new functionality in btrfs inspect tree.

Before that, would you please try the following patch and to see if it
helps btrfs-restore to salvage any data?

------
                        break;
                fprintf(stderr, "Could not open root, trying backup
super\n");
------

Thanks,
Qu
