site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Terry, Thanks. Commenting the holding-a-simple-lock-while-entering-mutex assertion got me booting. I managed to get my code working, thanks to an assertion that triggered in the debug kernel when I passed the wrong task into IOMemoryDescriptor::withOptions using physical memory. No problem, glad to be of assistance! Can I ask for something in return? Cheers! -- Terry _______________________________________________ Do not post admin requests to the list. They will be ignored.

If this caught the problem for you, it would make sense that it could catch problems for other people. It would also be useful to know the criminal KEXT; if this one is too hard to track down with your setup, I'd understand if you said not to it, but it can never hurt to ask...
