Message-ID: <2cd5aca36f853f3c9cf1d46c2f133aa3@linuxsystems.it> (raw)
In-Reply-To: <585760e0-7d18-4fa0-9974-62a3d7561aee@linuxsystems.it>
btrfs + dmcrypt + compress=lzo + autodefrag = corruption at first boot
So discard is not the culprit. Will try to remove compress=lzo and
autodefrag and see if it still happens.
