Messages in this thread | | | Subject | BUG: stallion module cannot register it's ISR in a 2.6.10 kernel on a FC3 system | From | Burn Alting <> | Date | Fri, 18 Feb 2005 19:48:12 +1100 |

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
