The only line is the following one. There is no other relevant error message 
besides that one. Could it be a hardware problem or simply a long device 
time out that triggers the dump? It is an old DAT that I use. Strange though 
that happened right after the upgrade.

Jul  3 22:53:16 ene /kernel: (sa0:ahc2:0:6:0): SCB 0x5 - timed out
