since failure is at random group profile it indicates to me that
btrfs kernel did not see the newly created btrfs on the device
To note: I have the following patch on the kernel which
is not yet integrated, but its not related to this bug.
btrfs: RFC: code optimize use btrfs_get_bdev_and_sb() at btrfs_scan_one_device
I guess the error was caused by this patch,
Yep. I got that understanding when you mentioned about the patch
btrfs: access superblock via pagecache in scan_one_device
