I also get, from time to time, a degraded array (raid 5), and always with
the same disk. And no, the hard disk is OK as rebuilding the array is
always possible. In my case the degraded status "always" comes when
booting and never on the live system.

I call this "false positives" but I'm a bit tired of this behaviour (I
thought hardware raid controllers are more stable :-/)

Look if there is any BIOS update/firmware revision or a new driver
available for the controller or even for the BIOS of the motherboard. I
would also ask the manufacturer.
