Why? It's quite clear that this is a hardware failure. I tested a live CD 
and PXE booting on it with the same problem before buying the new card. I 
also tested the system disk fine in another machine. It's got nothing to 
do with the system, although it happened right after the update/reboot.

So, other than replacing the mobo, it *is* the solution. Mobo might be 
going haywire next as well, but currently it's absolutely stable. And I 
have a backup now in case it wants to go ...
