I have booted 2.5.34 and 2.5.36, the same controller as yours, on my dual PIII box and it is apparently functioning well. I have not done any kind of load testing yet. Congratulations! I presume you are now the DAC960 maintainer, subject to approval from on high of course, and assuming you are willing. I'd like to do some spelling changes, just obvious ones for now, like removing spelling wrappers from standard kernel interfaces.
