[1.] One line summary of the problem:
After power loss, seg fault on boot tracing to fs/f2fs/recovery.c:270
[2.] Full description of the problem/report:
Laptop running Arch Linux kernel 3.10.2-ck, booting with the EFI boot stub using rEFInd. The machine has a Samsung 840 SSD with the root partition formatted to f2fs. Laptop battery must have run down without the system hibernating or shutting down gracefully. Boot fails with a segmentation fault reporting a bug at fs/f2fs/recovery.c:270

[4.] Kernel information
Running kernel 3.10.2-ck-nehalem kernel. This is a kernel version patched with Con Kolivas' patch set, and compiled with optimizations for the nehalem architecture. Although the most notable difference in this patched kernel is the BFQ io scheduler, I am using the CFQ io scheduler on this machine.
[4.1.] Kernel version (from /proc/version):
Linux version 3.10.1-2-ck (squishy@ease) (gcc version 4.8.1 (GCC) ) #1 SMP PREEMPT Sun Jul 14 07:14:59 EDT 2013
[4.2.] Kernel .config file:
I am sorry, I don't have this on hand at the moment. If this is critical, I can boot this machine off of a USB iso and try to track down the config file.

Hi,
Thank you for the report.
If possible, could you run fsck.f2fs to the failed device?
Otherwise, can you send the disk image to me?
Thanks,

No problem. Since the Arch repo's version of f2fs-tools does not include
fsck.f2fs, I built it from your git repo
(git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-tools.git)
using an Arch Linux install usb on the same machine, with Linux
3.9.8-1 .
The output on the main system partition is:

I also ran fsck.f2fs on these partitions with higher debug levels, but
the output files are somewhat large, so I won't bother sending those
unless you need them.
Thanks,

Hi,
Thank you for the report.
If possible, could you run fsck.f2fs to the failed device?
Otherwise, can you send the disk image to me?
Thanks,

Hi,
Very unfortunately, such the *unreachable NIDs* error was resolved by
the recent patches fixing several recovery routines. So it needs to use
the latest F2FS source urgently.
Even the worse thing is that we don't have fsck.f2fs fixing the file
system consistency, so that it needs to reformat the failed disk.
Sorry for that.
But, I strongly convince that most of recovery bugs have been fixed so
far. Hence you can believe that the current F2FS is very much stable
than ever before.
Thanks,

Thank you very much for looking into this. I'm glad to hear that it is a
problem that has been resolved upstream. Everything important on the
disk is backed up elsewhere, so reformatting is no big deal.
Thanks again,
Ray

Hi,
Very unfortunately, such the *unreachable NIDs* error was resolved by
the recent patches fixing several recovery routines. So it needs to use
the latest F2FS source urgently.
Even the worse thing is that we don't have fsck.f2fs fixing the file
system consistency, so that it needs to reformat the failed disk.
Sorry for that.
But, I strongly convince that most of recovery bugs have been fixed so
far. Hence you can believe that the current F2FS is very much stable
than ever before.
Thanks,
