Subject: x86-64 2.6.15-rc2-git5 fails to boot with 4GB memory
Date: Tue, 29 Nov 2005 05:31:02 +0200	[thread overview]
Message-ID: <20051129033102.GA5706@mea-ext.zmailer.org> (raw)

With 2 GB in place, the kernel boots just fine, but with
4 GB, it reports:

 kernel direct mapping tables upto ffff 8101 5000 000 @ 8000-f000
 PANIC: early exception rip  ffff ffff 8016 f002 error 0 cr2 4230
 PANIC: early exception rip  ffff ffff 8011 d1fe error 0 cr2 ffff ffff f5ff d023

and some other lines, which I didn't jot down on paper...
These were copied from some Fedora Core development kernel version
after 2.6.15-rc1 (last working one) in a box with 4 GB memory.

Those hex values didn't have intermediate spaces in them, though.
That was me trying to understand 64 bit values.

Last working kernel with all 4 GB memory in the box was  2.6.15-rc1
Since then the kernels have failed to boot at all, unless machine
PHYSICAL memory is stripped down to 2 GB.  Command-line options
(e.g. "mem=2G") don't help at all.
