To: Thermionix; +Cc: linux-btrfs
your test case is same as in the patch below
and the panic was due to null bdev (which matches
in your logs).
[RFC PATCH] btrfs: fix null pointer deference at
btrfs_sysfs_add_one+0x105
But in your logs below, there isn't a panic right ?
wrong cut and paste ? or what did I miss?
Thanks, Anand

those are the last useful log outputs before the server locks up
digging in /var/log/messages - you can see it stopped logging at 12:47, and I hard reset at 3:07
maybe I should have specified hard-lock-up instead of panic

Something happened even before the kernel messages you posted, as this kernel is already tainted. I would honestly try to get a prebuilt 3.14-rc1 kernel from your distro's dev branch, or build from mainline. There are a large pile of bug fixes from just 3.13, let alone 3.11.6.
And also make sure you're at btrfs-progs 3.12. If the kernel alone isn't able to work around it with a normal mount, or -o recovery, or -o recovery,degraded, then your next step is probably btrfs-zero-log based on the btrfs: failed to read tree root on sdg.
Let's see if others concur.

Mostly the above Bug is fixed in the patch below..
[RFC PATCH] btrfs: fix null pointer deference at
btrfs_sysfs_add_one+0x105
If you are hitting the same panic again, could you test it ?
Thanks, Anand
