I have attached the file to this email. My kernel is fairly stock, with amr, nge, smp and DRM_DEBUG enabled. I can make my config file available as well as the full hardware specifications for the machine that this was found on. Google turned up something similar from last December, involving the same line of code, but it was a LOR. That report can be found here: http://lists.freebsd.org/pipermail/freebsd-current/2003-December/015540.html Any ideas?
