Hope you all had a great Xmas and New Years! :)

I managed to get linux to visibly start executing through smc1 - it
turns out that I had chosen the standard generic serial support option,
when it was in fact, non-standard... oops!

A new year, new problem... i'm afraid :(  Here's a short listing of
what I see at bootup :

## Booting image at 01000000 ...
   Image Name:   Linux-2.4.19-pre7
   Created:      2003-01-07   1:50:16 UTC

    eth0: status: link up, 10 Mbps Half Duplex, auto-negotiation

At this point, linux hangs.  Now, I'm not too familiar with what is
supposed to happen next - but according to the output that i had on the
fads860 board (i'm currenlty working on a custom design, mpc860T board),
I am supposed to get something like:

Tue Jan  7 11:23:43 2003
VFS: busy inodes on changed media.
mount: Mounting /dev/ide/host0/bus0/target0/lun0/part1 on /mnt/idedisk

 BusyBox v0.60.3 (2002.07.16-02:05+0000) Built-in shell (ash)
 Enter 'help' for a list of built-in commands.


I can ping and telnet my target (sometimes) and i can get something
like the above - however, i have to login and exit telnet to type
anything at the prompt.  

Now, each time I do a "date" , I get the exact same response - i.e., my
RTC seems to have halted.  I don't get it... I can do "date" in PPCBoot
and my seconds change.  I put in some register dumps and I get:

TBSCR: 0x00000103
RTCSC: 0x00000013
RTC:   0x5fffc058
PISCR: 0x00000004
SCCR:  0x03800000

how do i get my clock to tick??

Thanks in advance,
My Hong Vuong
