Hi. I am seeing the same behavior on two unstable branch systems that I
upgraded to kernel-image-2.4.3-k6/7. They were both running 2.4.3 kernels
that I had compiled with no problem.

I get the same error. "lilo -P ignore" seems to work around it, in that
it installs the boot sectors and everything works. If you run lilo under
an earlier kernel (ie. not a debian 2.4.3 kernel) then lilo will stop
complaining.
However, "lilo -P fix" seems to screw things up quite badly. I tried that
on one system, and now if I go back to an earlier kernel (the
2.2.18pre21 from potato, which is one of the few I have boot disks
for) and try to run lilo, I get the same error. Also, I cannot currently
get it to boot from that lilo boot block.

I suspect that if you boot another kernel, your disk geometry will look
quite different. When I boot with the 2.2.18pre21 kernel I get a much
different disk translation, and the partition sizes all work out okay. The
cylinder units were bigger, too, so there were less cylinders.
Also, in response to another poster's suggestion: if you resize the
partitions using gpart, then you ever have to go back to an older kernel,
won't you will have the same problem?
