Subject: hotplug: Fails to load firmware for ipw2200 after upgrade

Date: Mon, 28 Feb 2005 22:56:01 +0000

Package: hotplug
Version: 0.0.20040329-17
Severity: normal

I've been using ipw2200 successfully with the previous hotplug
version, 0.0.20040329-16.  Following a dist-upgrade, my hotplug was
upgraded to 0.0.20040329-17, and after the next reboot, my ipw2200
wireless driver could no longer get its firmware loaded (via
hotplug).  Reverting to hotplug version 0.0.20040329-16 (and making no
other changes to my configuration) caused the problem to go away.

Lines logged in /var/log/kern.log as follows (for the broken case):

Feb 28 22:31:38 localhost kernel: ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.0

Feb 28 22:31:48 localhost kernel: ipw2200: probe of 0000:02:06.0 failed with error -5

Of course, it may be that the bug is in ipw2200 or somewhere else.
I've built ipw2200 from the debian package ipw2200-source, version
1.0.0-1, running on standard Debian kernel image 2.6.8-1-686.

For reference, when it works (using the previous hotplug), I get this
logged:

Feb 28 22:36:23 localhost kernel: ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.0
Feb 28 22:36:23 localhost kernel: ipw2200: Copyright(c) 2003-2004 Intel Corporation

Feb 28 22:36:23 localhost kernel: ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection

Also, I certainly have the right firmware files is the right place:

$ pwd
/usr/lib/hotplug/firmware
$ ls
ipw-2.2-boot.fw  ipw-2.2-bss_ucode.fw  ipw-2.2-ibss_ucode.fw
ipw-2.2-bss.fw   ipw-2.2-ibss.fw

Ah, is it possible that having these as symlinks could cause a problem
for hotplug?  As you can see below, I have them all symlink'd into /usr/local.
(The links are not dangling - see wc output.)

$ ls -l

Any ideas?

I do not know what -2 means, but I see that it fails after the timeout
so I think that the agent is not even trying to upload the firmware.

What happens if you unload and then reload the module?

The changes to firmware.agent between the two versions are very simple,
can you also check what happens if you use -17 with the firmware.agent
file from -16?

Are you using udev?

No, files are checked with -e.

It does the same, i.e. fails in the same way with the same log message.

OK, this makes no difference.  Using the older firmware.agent with the
newer hotplug fails in the same way.

Yes, using udev.  Does this help to explain it?

Maybe. Try to comment the line in /etc/init.d/udev which updates
/proc/sys/kernel/hotplug and reboot.

OK, this fixed my problem.

I commented out the following line from /etc/init.d/udev 

    echo /sbin/udevsend > /proc/sys/kernel/hotplug

So, everything works again for me, and I'm happy.  Thanks for your
help.  

Is this then a bug in udev (for which I see you are also the Debian
maintainer)?  Is there anything else you need from me?

cheers,
Simon

It got upgraded with everything else, so now on 0.054-1.

It's all in lib/kobject_uevent.c and should be trivial. It was changed
to increment the seqnum counter only if the kset wants to emit the
event.

I should be safe, I think.

This kernel will not work correctly with managed events. It has holes in
the sequence numbers. You need at least 2.6.10 if I remember correctly.

The bug still exists and you should not close it unless the

Sounds suspiciously like it will alter the kernel ABI,
but if you have a patch please send it here.
