Description Jon Benedict 2006-05-25 21:38:08 UTC 
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): 

kernel 2.6.9-34


How reproducible:  

Install serial card with dongle/break-out cable, install OS

Steps to Reproduce:
1. Insert Hardware
2. Install RHEL 4 AS u3 x86_64

  
Actual results:

Only 1 serial port is useable 


Expected results:

All 8 ports should be useable


Additional info:

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
Intel Xeons

Here is some card related output:

---

[root@dev-laps-svr2 ~]# dmesg|egrep -i "serial|sealevel"

Patch supplied by Sealevel, the manufacturer of the card
Comment 2 Alan Cox 2006-05-25 21:45:47 UTC 
I agree with this patch (matches upstream).
Comment 3 Linda Wang 2006-05-26 19:27:41 UTC 
Do we have the hardware to test here at Westford? If not, can someone
tell us how to gain access to test?
Comment 5 Aristeu Rozanski 2006-08-22 21:25:21 UTC 
any news on the acquisition of this hardware?
Comment 6 Jon Benedict 2006-12-06 20:55:13 UTC 
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.
