I never had this, however, my understanding is that this is related to
ext3 journaling filesystem (as this is kjournald that is blocked for 2
minutes), not to RAID (which would be mdadm, mdX_raidY and the like...),
and that it shouldn't be blocking anything apart writing the journal.
Was the server in a frozen state when this appeared in your log?
Just my 2 cents guess here,
