assertion in journal_start



Hi,

I have a server configured as follows:
  a standard 2.4.18 kernel, IDE discs, 1Gb RAM (not all used), load avg around 1-2.
  a large partition, formatted reiserfs
  within large partition are 80 300Mb loopback file systems, formatted ext3.

I got the following assertion yesterday which forced a lot of processes
into D state.  I'm not sure how easy it is to reproduce this problem.

Assertion failure in journal_start() at transaction.c:226: "handle->h_transaction->t_journal == journal"


The oops follows:
