strange Lilo problem

Hi all. I don't remember when this started; however, whenever I go to reboot, I
find that the default kernel never boots, even after the timeout value has been
exceded. Instead, I have to actually select which kernel I want to boot out of
the list. Anyone have any idea why Lilo would seemingly refuse to boot the
default kernel, yet I can boot it if I hit 1 for example? I am currently using
Lilo-22.8 that I compiled about a year ago. Thanks!
