I've had mine lock up at more or less the same point.  I got rid of
/etc/rc.d and it just quit after adding swapspace.  I got swap out
of my /etc/fstab, and it just quit after "VFS: Mounted root (ext2...."

I later (after hitting the problem twice (and reinstalling to get rid
of it twice)) realized that it would lock up like this only after I 
shutdown from someplace other than the console (like a telnet session
on a win95 box here in the soho lan, or an xterm).

Is it right that you can't shutdown from anywhere but the console?
BTW, When my boot sequence locked up, I could still log in from a
non-console terminal.  Maybe you can do that.  The problem is that
if I did that, my machine thought that the terminal I logged in at
was the console!  Really wierd.  It would try to treat that terminal
(a telnet session from win95) as the console!  After I logged in over
telnet, the console would show a login prompt, but if you logged in,
the console would be treated as a terminal!

Just $.02 that I hope will contribute to figuring it out.

Background: Slackware from Infomagic Nov. 95 CD.  Kernel 1.2.13.

I had a similar problem when I moved my computer.
The first time I booted it up, I started X-windows, and issued
'shutdown' from an xterm...big mistake.  After that, the machine booted,
froze at the spot yours did, and eventually propmted for a login.
It let me log in but my mouse didn't work and X-windows would
no longer start.  After about two days of continous work, I found a solution
that works although it seemed kinda radical.  
  I read in some how-to that /dev/console should be a symlink to /dev/tty0.
On my machine, however, /dev/console wasn't a link to anything but /dev/systty
was a link to /dev/console.  So I deleted /dev/console and then
'ln -s /dev/tty0 console' from /dev.

Now everything works fine, xwindows, mouse, virtual consoles and everything.

go figure....use at your own risk.
