It looks like the patch cures my original, real, problem, too. It probably 
saved my day (or those of the 250 people with their home dirs on my file 
server) or my entire weekend. Without it, I would have lost one RAID 
component at 02:05 and a second at 12:17.

I still don't know what the root cause for the ,,Phy x: Link Status Unknown'' 
events is, but at least, I now survive the following timeout.
