Default Re: AGP not working (FreeBSD 6.1, NVIDIA 96.31)

This actually is the intended/correct behavior (aside from the crash tbyte mentioned, I'd be interested in more details on it) with driver releases more recent than 1.0-81xx when using the FreeBSD AGP GART driver; this driver does not update the kernel mappings of memory mapped into the AGP aperture, which typically leads to severe stability problems with AMD Athlon processors.

You can force the driver to allow this configuration at your own risk by editing the file src/nvidia_subr.c (search for nv_no_incoherent_mappings()), but this will only work reliably if the AGPGART driver is fixed.
