Hello,

I've been getting the following "BTRFS errors" for a while now, the wiki 
[0] advises to report such occurrences to this list.

BTRFS critical (device sda2): corrupt leaf: root=466 block=194756837376 slot=72 ino=1359622 file_offset=475136, extent end overflow, have file offset 475136 extent num bytes 18446744073709486080

BTRFS error (device sda2): block=194347958272 read time tree block corruption detected

I can reproduce these errors consistently by running `updatedb`, I 
suppose some tree block in one of the file it reads is corrupted.

Thanks in advance for your help,
Regards,
Samir
