Red Hat Bugzilla – Bug 193185
support for Sealevel 8 port serial card
Last modified: 2007-11-30 17:07:25 EST
Description of problem:
Sealevel 8 port serial card is not currently supported in the version of the
kernel distributed by Red Hat. According to the manufacturer, it is supported
in kernel 2.6.12
Version-Release number of selected component (if applicable):
Install serial card with dongle/break-out cable, install OS
Steps to Reproduce:
1. Insert Hardware
2. Install RHEL 4 AS u3 x86_64
Only 1 serial port is useable
All 8 ports should be useable
Customer (ITT Systems at Patrick Air Force Base) recompiled stock kernel with
patch, included below, and the card worked. This was on a Dell PE 6850 w/ 4
Here is some card related output:
[root@dev-laps-svr2 ~]# dmesg|egrep -i "serial|sealevel"

Patch supplied by Sealevel, the manufacturer of the card
I agree with this patch (matches upstream).
Do we have the hardware to test here at Westford? If not, can someone
tell us how to gain access to test?
any news on the acquisition of this hardware?
The customer had actually added this patch to the kernel while I was there in
May. The card was recognized and all 8 ports were working.
