Everything works perfectly, actually better than > ever. We recently added some error detection & reporting to the driver. On some machines it's picking up what I think are errors in the initial mode programming (possibly by the BIOS), where the display base pointers are pointing at invalid addresses. We fix those up shortly after loading the module so the error should be harmless, but it would be nice to get rid of it. -- Jesse Barnes, Intel Open Source Technology Center -- 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/
