As I sadi elsewhere I dropped highmem support for now as the 33-rt hackery to make it work is just ugly as hell and anything above 4G is even in mainline a complete disaster. If possible, just run a 64bit kernel on your machine (you can still use 32bit userspace) or you have to wait until someone comes up with a reasonable fix for that problem, unless you are the one tackling it :) Thanks, tglx -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
