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 ([email protected]) (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

[X.] Other notes, patches, fixes, workarounds:
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.
