I didn't notice a corruption on other filesystems with kernel 3.17.0.
Also I didn't experience any hangs except when trying to mount a
corrupted btrfs but this was causing a hang within less than 10 seconds.
It could be that your problem is unrelated and that the corruption you
are experiencing is due to an unrelated hang followed by a hard
powerdown. Have you been able to capture any btrfs related kernel panics ?

Howdy,
So I run several gentoo systems and I upgraded two of them to kernel
3.17.0
One using BTRFS for root.
One using ext3 for root (via the ext4 driver)
_Both_ systems exhibited strange behavior (long pauses and then hangs
requiring hard-power) within several hours. Both then had random
filesystem damage.
On the BTRFS system much of my browser settings for firefox were
trashed, particularly the cookies and saved conifigurations for
add-ons (like which sites had scripts enabled/disabled in no-script) etc.
On the ext3/4 system there were several corruptions including a
pipe/special file with a large non-zero size that required I do a
"fsck -fyD /dev/sda3" to repair. (one comment from fsck was that the
pipe/special file "looked like a directory" or some such)
So I can say that corruption is taking place, but I suspect it is
_not_ happening in the BTRFS specific code.
(ASIDE: both systems are older amd64 using built-in radeon display
hardware.)
