A workaround for the monitoring issue is switching to the megaraid2
driver. The megaraid2 driver includes useful statistics in /proc which
can be used to monitor the raid.
Some shell script examples are found in the archive. The basic thought
behind the shell scripts is to diff the current /proc content against a
known good configuration.

My cerc config is the same, consisting of 2 80GB disks.
