Re: serial console support broken (bug #12922)

[Philip J. Hollenback]

Here's a followup in case anyone else gets bit by this.

The problem is in a Redhat patch to grub.  See my bugzilla report

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=156836

for details.  Basically putting a splashimage line in your grub.conf
has the side-effect of disabling the menu on the serial console.  It's
hard to consider that anything but a bug.

but as I said, I think it's in a fedora patch to grub, not the
pristine grub source.
