Normally the answer would be "Closed driver, complain to nVidia", but just in case.. First I suggest you try the new drivers that came out for it today first though, to see if that fixes your problem. > Jeff Hartmann (AGPGART support) thinks this is probably a MTRR issue. > I'm leaning that way, given a recent posting by someone else having > MTRR problems with his Cyrix 6x86. The recent problems were only in Alans 2.4.2-ac tree, not in the main Linus branch. They should also have only happened on Athlons that was introduced by the addition Cyrix III support. 2.4.2-ac20 fixes this. As no-one else afaik has complained about Cyrix MII MTRR support, I think this is an isolated incident, which is why I'm pointing a finger at the binary drivers, but... There is the possibility that you're the first MII owner to notice that this is broken. Can you verify that.. a. You have MTRR support compiled into the kernel. b. You have a /proc/mtrr file c. You can add/delete ranges using /proc/mtrr (See Documentation/mtrr.txt for info on how to do this) If yes,yes,yes, it is a broken driver, and you should complain to nVidia, not linux-kernel. regards, Dave. -- | Dave Jones. http://www.suse.de/~davej | SuSE Labs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
