I'm also using (for the first time) H. Peter Anvin's autofs patch, version
0.3.7. That patch doesn't change init/main.c and doesn't contain the words
"serial" or "console," and when I apply it to plain Linux 2.0.30, I don't
have the problem. I'm not using any other patches at all. In particular,
I'm not using the serial console patch. I tried using the init/main.c from
Linux 2.0.30, #if 0'ing the section above, replacing
drivers/char/console.c with the original version, and changing the
"vga = 6" line in my lilo.conf to "vga = 0" but all these (one or two at a
time) failed. I'm using an old VGA card, a Video 7 I think.
Here's the configuration I'm using for the kernel:

Here's my lilo.conf:
