I'm not sure if this is too much to ask, but can you two try one of the following things? Not both, just one of the two would be fine... Option 1. Try downgrading from 4.7-STABLE to 4.7-RELEASE. This should be relatively easy (and safe) to do, since 4.7-STABLE hasn't changed a lot since 4.7-RELEASE. If the problem persists with 4.7-RELEASE you should definitely try your best with option 2. Option 2. Try reading the "Developer's Handbook" section on debugging kernel problems, and attempt to build a kernel with debugging symbols. Then when the next crash hits, use the kernel debugger to get a stack trace of the kernel and post that to this list. The Developer's Handbook is available both locally (if you have installed the documentation packages) under /usr/share/doc/en/books/developers-handbook or online at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/ - Giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
