Red Hat Bugzilla – Bug 13564
secondary serial console doesn't work anymore.

Lilo doesn't work properly w/ serial console _if_ the serial console is
a secondary console. Ie:
Doesn't work: LILO-prompt won't appear, you won't see the kernel messages
If the positions of console= definitions are reversed, it works _almost_ as
it should. It doesn't matter whether message= has been defined in
Almost: you get only 'LILO' message. If you hit any key, you get to the
normal lilo prompt alongside with 0x40 error. After that, everything seems
to work fine.
Downgrading lilo to the one shipped w/ Red Hat 6.2 makes it work again.
I tested this a bit, with and without special patches.
The big, Stormix-adapted graphical boot menu -patch is causing the problems
here. I left it out of the RPM, and serial console works fine.
Preston hacked in lilo-0.21-graphical.patch, assigning to him.
More analysis on this revealed a couple of things:
1) without message=, LILO Prompt appears ok and it accepts user input
2) After that no kernel messages are shown, either in booting or in shutdown
(stopping md processes).
3) I've had lilo freeze after 'Loading linux...........', killing the boot
process twice now. The computer had to be resetted; the VGA screen didn't show
anything other than that 'Loading linux...'. I'm not sure if that's coincidence.
Anyone interested in testing this, btw, should be able to check it out without
serial console by using:
Now, kernel messages after Loading linux... should be shown on monitor (but aren't)
Seems to work in beta5.
