Thanks for the tip Willy,

The hardware is the ActionTec DualPC Modem it has a conexant cx82100 
arm processor.
I can reproduce it at will by connecting to the internet and running 
nttcp thru it at the same time
I am scping file both ways from and to, and then finally starting a 
getty on /dev/ttyS0, the modem is
at ttyS1 and also ttyS0 is where all the kernel printk messages come out.

When I start the getty if I have all the other traffic going it 
usually will panic in under a minute. IF I don't
have the getty running it will run for hours and not panic.



2.4.32-uc0 with patches from
http://www.bettina-attack.de/jonny/view.php/projects/uclinux_on_cx82100/
