Hi Andi,
With this patch in 2.6.15-git12,
(http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=6c5acd160a10c76e8debf4f8fa8256d7c914f290),
I found that kernel could no longer boot when I include "mem=1G" boot
option on a dual Xeon machine that has more than 4G of memory. The
machine boots normally without "mem=1G" specified or when the patch is
backed out.
I have included the boot log of the failed boot and the normal boot for your
reference. The table_start was relocated from 0x8000 to 0x100000000
with the patch applied.
Regards,
Tim Chen
