The advice I received worked great. I no longer see the 10 minute delay at system startup. Below is a summary of the steps I took to build and run a 10.6.2 kernel. However, I would still like to know why the AppleProfileFamily kext needs to be disabled. Could someone shed some light on exactly how the AppleProfileFamily kext is dependent upon the specific kernel that it ships with? Thanks, --Jim Building 10.6.2 kernel: 1. Build xnu kernel using instructions at: http://shantonu.blogspot.com/2009/09/mac-os-x-kernel-source-xnu-has-been.htm... 2. Install new mach_kernel file on test partition. 3. Disable AppleProfileFamily.kext by removing it from the /System/Library/Extensions directory of the test partition. 4. touch /System/Library/Extensions directory of the test partition. 5. Boot up the test partition! --------------------------------------------- After you install the new kernel, on the same partition, touch SystemLibrary/Extensions The first time it reboots it will rebuild the kernel cache. After booting successfully once, it will boot fast again. -- Terry --------------------------------------------- Date: Thu, 26 Nov 2009 14:58:15 -0500 From: nawcom <nawcom@nawcom.com> Subject: Re: Building 10.6 kernel? To: darwin-kernel@lists.apple.com Message-ID: <4B0EDDD7.7070107@nawcom.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed What I have been doing since the first xnu src for darwin 10 came out is using a kernel extension to prevent any of the kexts of and within AppleProfileFamily.kext from loading. If you'd like to see the source code for this kext let me know, but simply removing the kexts and subkexts inside of it does the same thing. Give this a try James, move AppleProfileFamily.kext out from /System/Library/Extensions to some other place and rebuild the Extensions.mkext (can be done with a simple: sudo mv /System/Library/Extensions/AppleProfileFamily.kext /System/Library; sudo touch /System/Library/Extensions) and reboot, launching your compiled kernel. you will see that you won't have to wait 10 minutes and there will be no losses or effects in performance or anything in the OS itself. I still haven't been able to get information from Apple on how to solve this issue, but this is what I have been using as an effective solution to the problem. -nawcom --------------------------------------------- Nix, James L (IS) wrote:

The instructions at:

work great. I had no problems building the kernel. The problem is that when I install the new kernel, my test machine takes approx. 10 minutes to boot. Actually boot works ok, but the machine hangs prior to login -- just after the SecurityAgent launches. It hangs for about 10 minutes and then proceeds normally. It's as if some process is timing out.

When I ssh into the machine and run top, I notice that the hidd process is "stuck". If I kill the hidd process, it restarts, and the machine immediately becomes responsive.

Any ideas? Are there some kernel dependencies that I am overlooking? By the way, this happens with all three versions of the 10.6 source available at opensource.apple.com.

Thanks,

--Jim
