I do have some observations: - "device agp" is commented out. Is there any particular reason for this? Does the machine not boot with it on? nForce chipsets provide generic agp support. - atapicam is currently broken on CURRENT. See sos@'s recent ata-mkIII headsup announcement for additional details. You might also want to take note of the following: - You are specifying a "maxusers" parameter. This is no longer required for normal operation. The kernel does a pretty good job of auto-tuning itself. I presume there is a reason for having selected such a low number. - The default scheduler in CURRENT is 4BSD not ULE (This might cause you to encounter edge cases down the road). - You commented out "device random". This causes your system to use alternate (and arguably less secure) entropy sources for its PRNG. I haven't really taken a look at the ASL yet. There are people on this list that are better qualified than myself that could lend you a helping hand with it in far less time than I ever could. I added one such person on the CC list... :-) Cheers, Andy | Andre Guibert de Bruet | Enterprise Software Consultant > | Silicon Landmark, LLC. | http://siliconlandmark.com/ >
