Problem with firmware load on ipw2200

Problem with firmware load on ipw2200

[Larry Finger]

I'm trying to help an ipw2200 user on the openSUSE Wireless Forum and I'm
stuck. The system is failing to load the firmware with error -2 (File or
directory not found). The difficulty is that the required files are
present with the correct permissions.

What system component might be missing and/or borked to get this symptom?

Thanks,

Larry

Or udev; basically whatever firmware helper is registered with the
kernel for firmware request handling.  Which these days I thought was
udev on most distros.

Older versions of compat-wireless had a race condition in the firmware
code that could cause that.  From the log of the compat repository:

commit 524449c0184d44773d4947db8cd3bfd98a0a215f
Author: Grazvydas Ignotas <notasas@gmail.com>
Date:   Thu Apr 22 16:54:02 2010 +0300

    compat: fix uevent_suppress on 2.6.29 or older kernels
    
    Missing uevent_suppress is causing two uevents instead of one, which is
    confusing udev and sometimes causing firmware load to fail due to race
    condition, so let's add it.

Thanks to all that responded. The problem turned out to be a missing
package that contained the compat-wireless scripts. The device is now
running - another satisfied "customer" that just converted his wife from
Windows to Linux. We get em one box at a time.
