Seems to be some kernel change. Thank you for quick response. I tried to reproduce this problem on my machine by using an ia64 linux-2.6.26 discontigmem kernel, but it could not do it. makeudmpifle did not fail. I want to know whether this problem depends on the kernel or either the machine. Could you send me the kernel .config file ? Thanks Ken'ichi Ohmichi
