Hi
I decided to post on a wider audience. So far the uml vmlinux gets block on
bootup at
page_ok(top) -> n = *address;
when calculating the top of the address space.
So my only guess so far is that the RHEL 5.0 has the option:
CONFIG_DEBUG_HIGHMEM
enable and the Ubuntu does not.
If I change the top starting address from:
unsigned long top = 0xffffd000 >> UM_KERN_PAGE_SHIFT
to
unsigned long top = 0xf0000000 >> UM_KERN_PAGE_SHIFT
it works.
Does anybody know why it would be?
Thanks
David Rodriguez
