No, when the MTRRs are wrong they would generally not work fine. As soon as something uses the uncached memory things go incredibly slow, slow enough to make the machine unusable. Sometimes you're lucky and nothing important is in there, but only sometimes. There is also no code in there currently to automatically limit the memory; the user has to do that with mem=... But I also don't like the panic. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
