Hi!
I am getting BTRFS hangs unregularily on SSD based BTRFS RAID 1.
Any hints?
If you need additional data please tell.
Raid is
merkaba:~> lsblk /dev/sda4 /dev/sdb3

I don´t know where this unknown, single chunk came from:

Btrfs v3.14.1
Last scrub from last week was okay, but I will rescrub after installing
3.15-rc7.
One quite reliable trigger seems to run make-kpkg -j4 to build a new kernel:
