Description of problem: 
ttyS1 on fenlason-lab2.lab.boston.redhat.com does not work well with the 
RHEL5B2 kernel. Many characters are getting dropped, and dmesg is filling with 
many lines saying 
ttyS1: 28 input overrun(s) 
(and other random numbers).  This makes the serial console to my rawhide box 
very hard to use. 
 
This hardware worked fine with RHEL4U4. 
 
Version-Release number of selected component (if applicable): 
kernel-2.6.18-1.2747.el5.i686 
 
How reproducible: 
Always 
 
Steps to Reproduce: 
1.minicom from the RHEL5B2 box to the rawhide box 
2.log in and cat /etc/motd on the rawhide box 
3.observe that the output is trashed 
   
Actual results: 
usually.  Sometimes you can cat /etc/motd successfully. 
 
Expected results: 
no garbled output
