I apologize for the delayed response, I was travelling.
Yes, the error message is the same as for the original report. Then it was triggered by a call to lsattr, now by calling btrfs to create a snapshot. The released kernels do not have the originally reported problem with lsattr but regressed with the call to create a snapshot. I originally found a regression when calling "btrfs fi show" which one only emit a one-liner with the program version but not the requested version with information about the btrfs partitions.
I have not yet had the chance to test the xenial or yakkety kernels.
