I would like to suggest that loadlin is a red herring. I use loadlin and
my machine also exhibits these reboot problems.
HOWEVER, I can ALWAYS reboot the system immediately after such a boot up.
I can ALMOST ALWAYS reboot after several hours, and SOMETIMES even after
several days, but this is very rare.
Unless loadlin is setting the kernel up in such a way that it fails later
then there is no connection between loadlin and the failure. If loadlin
DOES set the kernel up differently than lilo, then it needs to stop doing
that.
My suspision, and it's nothing more than that, is that something in the
kernel is inadvertantly clobbering the boot vector in memory (I
forget...it's either at 0000 or FFFE?) so that reboot jumps into the swamp
when it tries.

Luck,
