Hi, any more information about this bug? How much memory do you have?
What ext3 filesystems do you have mounted? The oops is in ext3 code:
handle_t *journal_start(journal_t *journal, int nblocks)
{
handle_t *handle = journal_current_handle();
int err;
if (!journal)
return ERR_PTR(-EROFS);
if (handle) {
J_ASSERT(handle->h_transaction->t_journal == journal); <----
handle->h_ref++;
return handle;
}
It seems to be related ext3's quota code -- and again it seems to be related to
an attempt to free memory when the system is under memory pressure. This looks
very much like a quota and/or ext3 bug.
