            Bug ID: 203588
           Summary: [ufs] fsck_ufs segfaults during journals after
                    powerloss
           Product: Base System
           Version: 10.2-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People

Hello,

I just had a powerloss with y desktop machine (which is not on an UPS). The
machine is running:

FreeBSD frodon 10.2-RELEASE-p2 FreeBSD 10.2-RELEASE-p2 #2 r287854: Thu Sep 17
11:37:46 CEST 2015     root@frodon:/usr/obj/usr/src/sys/CUSTOM  amd64

After reboot SU+J was unable to recover the journal (segfaulting). A full fsck
hopefully worked ..

I took a couple of screenshots which are available from here:
http://home.bebif.be/~jcigar/ufs/
I can provide more information if needed ..
