Kernel 3.16, e2fsprogs 1.43-WIP (1.42.11 compiled with metadata_csum
support), filesystems mounted with journal_async_commit.
This may be an fsck problem, hard to tell. I consistently have
problems with journal recovery after hard reboot when filesystem has
metadata_csum. Interestingly, no problems with 64-bit filesystems.
during journal replay, bogus block numbers are reported. in this
case, a 128MB file was deleted on two filesystems where the only
difference is 64bit vs non-64bit. This also happens with or without
bigalloc, though I only document bigalloc case here.
please see attached superblocks, dumped just prior to hard reboot.
