I suspect that changing the timeout may just hide the real problem.

Hmm, it is a non fatal error for gjournal, I'm kind of surprised it's a
fatal one for ZFS..

If the cache flush really failed (eg due to a stuffed disk) then there
really is a problem, but IMO it is likely this is going to be caught by
a read or a write operation very soon.

If it is a transient error then panicing seems to be about the worse
response :)
