Hi,

I have similar problems under load on one DualOpteron machine,
i noticed that when i set the controller in U160 mode the messages
dissaperar. So i split the drives in the server equaly on the both
scsi channels on the motherboard and set the controller to U160.
I have then run while(1) { make clean; make universe; } which is still
runnnig for about 3 days. Before that the machine was rebooting about
every couple of hours if under load.
 From what i understand this is not exactly a FreeBSD problem, but rather
a consequence of U320 being really hard on the hardware with pushing it
to the limits.
