Description Justin Georgeson 2003-03-15 22:50:12 EST

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030206

Description of problem:
I am Running Red Hat 8.0.94 with kernel 2.4.20-2.48. I have a Linksys WPC11 v3
(Prism 3) 802.11b card. Using an AP which broadcasts its SSID and no encryption,
the orinoco_cs driver mostly works. The driver periodically drops the
connection. When this happens pinging any hosts on my LAN (like the default
gateway) yields "destination unreachable." This is not an issue with inactivity,
I've seen this happen with several active connections.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Configure a wireless interface with the orinoco_cs driver, default settings
2. Insert a Linksys WPC11 v3 PCMCIA card
3. Go on about your work like normal

Actual Results:  Association to AP should stay up

Expected Results:  Association is randomly dropped.

Additional info:

If caught in time, simply running 'ifup <interface>' can fix it without loosing
any of my connections (ssh sessions, web sessions on secure sites, etc).

Hm, don't know who updated this to say RH 9, but I do still see it in RH 9.

I also see the occasional dropped connections.  WPC11 Ver. 3.0.  Most times this
does not affect much, I just to a /etc/init.d/network restart and everything is
fine again.

Sometimes it gives me a hardlock up as well.  The CPU pegges out at 100% (
ksoftirqd_CPU0).  Syslog shows lots and lots of this:

Apr  6 22:40:37 localhost last message repeated 1359 times
Apr  6 22:40:37 localhost kernel: hermes @ IO 0x100: Error -16 issuing command.
Apr  6 22:40:37 localhost kernel: hermes @ IO 0x100: Error -16 issuing command.
Apr  6 22:40:37 localhost kernel: eth0: Error -110 writing Tx descriptor to BAP
Apr  6 22:40:37 localhost kernel: hermes @ IO 0x100: Error -16 issuing command.
Apr  6 22:40:37 localhost kernel: hermes @ IO 0x100: Error -16 issuing command.
Apr  6 22:40:37 localhost kernel: eth0: Error -110 writing Tx descriptor to BAP

This is with RedHat 9, installed on a clean disk on a Toshiba Satellite Pro
model 4260.

It seems to happen every couple of hours or so for me.

I have the same problem with a Netgear MA311, and worked around it with newer
beta orinoco drivers compiled against the stock redhat kernel from
The problem doesn't completely go away, but it shows up a lot less. 
Comment 4 Benjamin Kosnik 2003-04-12 01:32:36 EDT
I can confirm this is still an issue. I'm running RH9 on 

1) IBM Thinkpad T30/D-Link 650
2) Dell 600 with Netgear MA401

The failure modes are identical, although for some reason I'm getting more,
quicker failures when I'm using static routes versus dhcp. Both of these systems
are up2date. After the connectivity drops, and the CPU usage pegs at 100%, dmesg
looks like lines and lines of this:

eth1: Error -110 writing Tx descriptor to BAP.

Does anybody have any work arounds or suggestions?

An errata has been issued which should help the problem described in this bug report. 
This report is therefore being closed with a resolution of ERRATA. For more information

this bug report if the solution does not work for you.

I still am experiencing this same problem with RH9 and 2.4.20-20.9.
