	This is fixed in the patches I've send to Jeff :
http://marc.theaimsgroup.com/?l=linux-kernel&m=105286597418927&w=2
	Just be patient ;-)

	I guess that if it's the only complain, this means that the
rest of the IrDA stack works for you in 2.5.X. At least, I'm not the
only one testing it...

Well, this got rid of the warning :) But actually when I stop irattach
(using Debian's init-script (/etc/init.d/irda stop)) my computer
freezes. This works (of course) fine with 2.4.21-rc2. I thought the
problem was the module unloading, but it seems to be something with
irattach instead. Sorry about that.

It works, but I get lots of weird/ugly/different messages. This is with
a SonyEricsson P800. Except for those annoying messages in my logs, it
works perfect :-)

I see I have gotten a ircomm_tty can't be unloaded as well. Hmm. Well,

Thanks.

	Disable HotPlug in your kernel and recompile. Various network
people have been notified of this bug, but this is not an easy one.

	Yeah, Martin should increase the debug level.

	This has been fixed in the latest BK.

You were right, this was the problem. Then I just have to choose what I
need the most; irda or pcmcia :)

Thanks :)

This and a few other things from the list which I've sent to you is done 
in my local codebase, but needs some testing over the weekend. So you'll 
see patches on monday. I guess I'll make them against what you've sent to 
Jeff despite it may need some more time until this appears in bk - Ok?

I bet pcmcia works without hotplug ;-)

IMHO the worst thing that might happen without hotplug would be one has to 
modprobe some drivers for CardBus cards by hand. But maybe I'm missing 
something because I'm not using hotplug...

Anyway, I really hope the network-hotplug deadlock issue gets resolved 
before 2.6.0 or we'll see quite a number of such reports then...

Martin,

If there is any code I can help test, I'm more than willing :-)

Me too - but no, wrt. the rtnl-deadlock nothing that I know of. The 
changes I mentioned above are merely cleanups of the sir-dev and irtty-sir
stuff completely unrelated to the deadlock.

I've just tried to ping the other thread but as was said, it's a 
network/hotplug problem and definitely not easy to resolve.

I might be blind or stupid (or both), but when I disable hotplug, I
can't enable cardbus at all. :) But davem's patch worked just fine :)
*happy*

Sorry for the confusion, you are right. I meant it works without userland 
hotplug stuff, but that's a mood point as you need to enable kernel 
hotplug to get the pcmcia option even presented - ENOTENOUGHCOFFEIN 8)

Yep, looks pretty good now.

irtty_sir cannot be unloaded

[Stian Jordet]

Hello,

I get this message when trying to use irda with 2.5.x. I know it has
been there for a long time, but since nothing happens, I wonder if
anyone knows about it? I don't really need to unload it, but when I
reboots (or shutdowns) my pc, it hangs at "deconfiguring network
interfaces". Which is quite annoying. I guess I can change my
init-scripts to now do that, but...

Module irtty_sir cannot be unloaded due to unsafe usage in
include/linux/module.h:456

Best regards,
Stian
