With this array I have to mount -o degraded, even though all devices are
present.

When I try and mount without degraded, I get this:

I'll let someone else handle the real technical stuff, but I distinctly
recall reading that a number of null-pointer bugs had been fixed for
3.10, and you're running 3.9, so I could suggest trying the latest Linus-
tree rc (3.10.0-rc5 just came out a couple days ago) or live-git HEAD.
I've been running 3.10-pre here with a (new) dual-SSD raid-1 data/
metadata both set of btrfs filesystems (I partition mine down, less eggs
in one filesystem basket), without issue so far.
Might nor might not be the same bug; as I said I don't get that deep into
the technical stuff, but it's worth a try.

I made a btrfs on five disks using RAID5 (-d raid5 for mount option). When a power failure occurs, I can not remount btrfs after my system reboots. Dmesg for remount is presented as following:
[ 192.713953] bio: create slab <bio-1> at 1
[ 192.716230] Btrfs loaded
[ 192.717177] device fsid a0dff7ea-9354-43fd-8516-0e17f370991d devid 1 transid 6 /dev/sdb

[ 192.720572] btrfs: failed to read the system array on sdb
[ 192.723398] btrfs: open_ctree failed
linux md raid5 have resync , the test seems btrfs raid5 have not resync,how fix the bug?

Have you tried 'btrfs device scan' before mounting it?

Please note that current implementation of raid5/6 is not completely
crash-safe, as was mentioned in the announcement (eg. here
http://lwn.net/Articles/536038/). The mount could fail if the parity of
metadata blocks is corrupted due to crash.
