Bug#297481: hotplug: Fails to load firmware for ipw2200 after upgrade

[Marco d'Itri]

What's wrong? The user is running udev 0054 with udevsend as the
hotplug multiplexer, if /sbin/hotplug is restored then the firmware
loader works again.
(In the report he talks about hotplug, but we later verified that udev
was upgraded at the same time.)

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

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.

This sucks, because the next Debian release will ship 2.6.8 as the
default 2.6 kernel. Do you know what needs to be backported to fix this?
What else does this break?

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.

>What else does this break?

I should be safe, I think.
