I talked to someone who knows at DPT; This is a knwon problem on certain motherboards. I suspect that due to age, etc., they will not fix this minor problem anytime soon.

Either Justin is correct and you walked on a firmware bug, or the new driver is missing something in the initialization, that was done correctly in the precambian days. I will look at it, once Justin has saturated his changes to the driver. > > If it is a transfer LED, then the DMA engine is stuck.

IF anyone (Justin?) needs access to it, just say so. Once Brass is passing regression, I will test on Nomis. Then Sendero, then performance...
