kernel BUG at fs/btrfs/extent_io.c:1893!
Hi, I have this problem after trying to run btrfsck. I have new 11 HDDs WD 2tb, on two RAID controllers Arch Linux, latest kernel. What I was doing was copying and reading multiple data at the same time After getting I/O errors while trying to access through samba and while trying to run a VM with files stored on volume, I ran a btrfsck but it failed.
