Here is the bug report. Stallion was purchased by Lantronix and they
don't really care about this bug.
[1.] One line summary of the problem:
Stallion 4 port IO card fails when modprobe'd into kernel
[2.] Full description of the problem/report:
Under Fedora Core 3 using a ftp.kernel.org 2.6.10 kernel, when
the stallion driver module is loaded into the kernel error
messages appear in /var/log/messages. Then, if a port is accessed
further messages appear and IRQ 11 is disabled/turned off.
[3.] Keywords (i.e., modules, networking, kernel):
stallion, serial, kernel
[4.] Kernel version (from /proc/version):
Linux version 2.6.10 (root@swtf.comptex.com.au) (gcc version 3.4.2
20041017 (Red Hat 3.4.2-6.fc3)) #1 Fri Feb 18 17:44:05 EST 2005
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
[6.] A small shell script or example program which triggers the
problem (if possible)
modprobe stallion

Hi Burn
Could you try the attached patch
It solved the same problem for me, it is NOT SMP safe due
to cli() calls, though will run fine on your system. I have been
running a console box for about 1mth non-stop with these applied.
The patch does two things it allows the driver to be built-in and
updates the call to request_irq, which is what is causing the
problem.
