I also have a m/board with i815e chipset, you do not mention which video card you have, mine is a Matrox G450 AGP. I have occasionally (much less often than you have) had a kernel panic. This seems to occur when I have loaded the agp module "by hand" so to speak, rather than as part of the startup procedures. My intuition is that the "agp" module is the problem, since I also get complaints from the kmod_drm module about it when I load that (I have reported the latter problem to the maintainer). I have not been able to create a reproducible scenario though, so I have not reported the "panic" thus far. So my hunch is that it is "agp", but as I say, that remains at the level of suspicion. <snip> -- Regards Cliff To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
