If the latter, do you see variations in kernel build time by simply > rebooting the same Image? I built it in a loop on the shell, so no reboots between builds.

I think build times should be comparable then since there is no fs caching. -Robert -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
