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 ?
