Please run the following command:
# btrfs ins dump-tree --follow -b 166456229888
It could be caused by the fact that btrfs-progs --repair doesn't handle
log tree well.
If that's the case, "btrfs rescue zero-log" should help.
But anyway, feel free to re-create the fs if zero-log doesn't help.
Thanks,

First of all, thanks for your help!
Did that:
root@mint:/home/mint# /tmp/btrfs ins dump-tree --follow -b 166456229888
/dev/mapper/sda3c > /tmp/btrfs-ins.txt
parent transid verify failed on 166475366400 wanted 127054 found 127060
Ignoring transid failure
WARNING: eb corrupted: parent bytenr 166456229888 slot 22 level 2 child
bytenr 166475366400 level has 0 expect 1, skipping the slot
The created btrfs-ins.txt is ~300MB in size, so i did not attach that
here. do you need id? then I can upload it to my owncloud and post a
link here.
after that i tried to zero the log:

Anything left to try?
