Distribution: Redhat since 5.2, Slackware since 9.0, Vector since 4.0
vmlinuz size doubled
I just compiled linux kernel 2.4.20 on slackeare 9.0.
Everything was fine except the vmlinuz size was over 2 MB.
About 1 month ago I also compiled the same source,
but the result was only 1 MB.
I realized that when I run configure the lilo.
It failed with error message "image too large".
Here is the ls l from the boot.
- vmlinuz-stock => original
- vmlinuz-old => first compilation
- vmlinuz => new compilation, the problematic one

This is strange.
The newer vmlinuz should be smaller since I removed many things such as SCSI support, Wireless, etc.
I reinstalled a fresh kernel source,
then copied the original /boot/config,
and did "make dep clean bzImage" again.
The result was more than 3 MB !!!
