  The assertion failing is:
        BUG_ON(nblocks > journal->j_trans_max);
in do_journal_begin_r(). That means that reiserfs_create() tried to start a
transaction with more credits than allowed by the journal.

  When did you started to see this problem? Also do you use SELinux (or
generally security labels)?
