Message:
The same bug exist also in kernel 2.6.25.20 and 2.6.26.8, and in the stable
release 0.7.7.
A function on kernel start was accessing page table behind the physical
memory limit.
SVN revision 1490 will fix it.

For me mem=640 and mem=800 works on system with 1536 MB total RAM. Windows
says in System overview, I have 1.5 GB. Tested with and without /PAE in
Windows boot.ini.

Of curse there exist a problem.
Tested some more with simple initrd:
colinux-daemon -t fltk kernel=vmlinux mem=648 initrd=initrd.gz
root=/dev/ram0
656 = 290h : OK
655 = 28Fh : freeze
654 = 28Eh : freeze
653 = 28Dh : freeze
652 = 28Ch : OK
651 = 28Bh : freeze
650 = 28Ah : freeze
649 = 289h : freeze
648 = 288h : OK
647 = 287h : freeze
646 = 286h : freeze
645 = 285h : freeze
644 = 284h : OK
That seams me a problem with 4MB bounding. Please try a memory, that can
div by 4 MB.
