I suggest using defaults for starters. The only thing in that list
that needs be there is either subvolid or subvold, not both. Add in
the non-default options once you've proven the defaults are working,
and add them one at a time.
Yes I read your previous suggestion and I already dropped subvolid, but
since the problem already happened I left it in the mail for completeness.
Anyway the culprit here is genfstab and that's probably what a beginner is
going to use when installing a distro:
https://wiki.archlinux.org/index.php/beginners'_guide#fstab
Disk is a SAMSUNG SSD PM851 M.2 2280 256GB (Firmware Version: EXT25D0Q).
The firmware is old if I understand the naming scheme used by Dell. It
says EXT49D0Q is current.
http://www.dell.com/support/home/al/en/aldhs1/Drivers/DriversDetails?driverId=0NXHH
According to this
(http://forum.notebookreview.com/threads/2015-xps-13-ssd-fw-problem-with-m-2-samsung-pm851.770501/)
the firmware you linked is for the mSATA version of the drive, not the M.2
one. EXT25D0Q seems to be the very latest one for my drive.
I advice using all defaults for everything for
now, otherwise it's anyone's guess what you're running into.

Would it be OK for you to test your btrfs on a plain ssd,
without encryption?
And just as Chris Murphy said, reducing mount option is also a
pretty good debugging start point.
Ok, I will remove dmcrypt, discard, compress=lzo, nodefrag and see what
happens.
I made a copy of /dev/mapper/cryptroot with dd on an external drive and
I run btrfs check on it (btrfs-progs 4.5.2):
https://drive.google.com/open?id=0Bwe9Wtc-5xF1SjJacXpMMU5mems (37MB)
Checked, but seems the output is truncated?
No, I didn't truncate the btrfs check output because it wasn't endless. I
just truncated the repair output.
I also have something new to report. Do you remember when I said that my
screen was black and so I had to forcedly power off the system? Something
similar happened today and since in the meantime I enabled magic sysrq keys
I have been able to recover this from the logs:

Thanks for reporting, I changed my dmarc DNS entry from quarantine to none.
I previously used reject and I hoped that quarantine was enough of a middle
ground to survive spam filters, but it seems I will have to get rid of
dmarc altogether.
Thanks,
