Just to pontificate for a moment, I notice that there's quite a few 
changes to the ATA subsystem that afternoon.  This might be significant as 
the Supermicro SATA controllers I use (a pair of AOC-SAT2-MV8 cards, 8 
port PCI-X things) aren't entirely trouble-free: when they're up and 
running they're fine, but they don't reset on reboot, even with the 
current (? 1.0c, anyway) firmware which causes problems rescanning the 
drives.  This could be a complete red herring, but I wondered if it may be 
related.

Chris.
