First, your kernel is totally outdated, you've been skipping 3 years of
fixes in 100 updates roughly covering 4600 bugs :

$ git log --oneline v3.4.9..v3.4.108 | wc -l
4683

7 of them directly affect reiserfs, and it's very likely that a number of
the other ones could as well :

$ git log --oneline v3.4.9..v3.4.108  -- fs/reiserfs/
15e5f90 reiserfs: fix race in readdir
b57644a reiserfs: Fix warning and inode leak when deleting inode with xattrs
a23d631 reiserfs: Protect reiserfs_quota_write() with write lock
8c7dcc4 reiserfs: Move quota calls out of write lock
8ed4d1c reiserfs: Protect reiserfs_quota_on() with write lock
394cbbc reiserfs: Fix lock ordering during remount
530258f tmpfs,ceph,gfs2,isofs,reiserfs,xfs: fix fh_len checking

So you first need to update your kernel to get the latest fixes. You're
lucky, your branch is still maintained!

Best regards,
Willy
