Description Robert M. Riches Jr. 2001-10-16 20:04:27 UTC
Description of Problem:
Whenever an X server is started or closed, that act (or
the PCI bus reset that seems to result) blows away the
login sessions of anyone using a serial terminal.  It is
likely the problem is somewhere other than /bin/login
(in util-linux), but util-linux was my best guess for
the guilty component.

Version-Release number of selected component (if applicable):

How Reproducible:
pretty close to 100%

Steps to Reproduce:
1. Person A logs in via a serial terminal.
2. Person B logs in via the console, starts an X server
   Person B logs out from the console, terminating an X server

Actual Results:
Person A's login session is blown away, and a login prompt
is issued.

Expected Results:
Person A's login session should not be affected.

Additional Information:
The serial ports in question are a Comtrol Rocketport 4-port
PCI card, using the open-source driver as modified by Harddata
to fix Alpha-related issues.  The driver is loaded as a module
into the 2.4.3-12 kernel.  I will attach /etc/inittab.  I'd be
willing to attach any other configuration files if needed.

There's zero chance of reproducing this bug without the exact same hardware
setup as you have.

I would guess that it is more likely a kernel problem (because it seems like
such a lowlevel thing), but I have no evidence at all. Since util-linux-2.10s
sounds rather old, you may want to try RHL 7.1 plus updates and see if your
problems go away.

You're basically on your own here. If you do come up with a patch that solves
it, I'd be happy to look at it though :)
