Does setting CONFIG_PCI_MULTITHREAD_PROBE=n fix it?

Yes and no. The BUG no longer occurs, but either ipw2200 or
NetworkManager is still not working. I am running Fedora development
(rawhide). For some reason, NM still cannot establish a connection
with this kernel build (this failed with 2.6.18-mm2 previously, but I
thought it was related to the BUG). "iwlist scan" can corrently
detect my access point. Also, I can use iwconfig and dhclient to
establish a working connection. NM fails with this output in the
message log (I'll try getting a more detailed debug log out of NM):

OK, thanks. Note to Greg: CONFIG_PCI_MULTITHREAD_PROBE+ipw2200 = oops.

Another reporter mentioned that he could only get his wireless to associate
with his AP by using essid "any". But that was a different type of card.
ipw2200 works OK for me, fwiw.
There's a largeish ipw2200 update in mainline now. That'd be worth testing.
It looks like that ipw2200 update was in 2.6.18-mm1 though. Did that work?

Yes, it did. My main problem with mm1 was the broken CPUFreq, which
is still busted in mm2. I am rebuilding with debugging enabled in the
ipw2200 driver. I'll see if I can capture any useful information when
I try to associate using NM.

argh. I'm afraid my head pointer keeps on wrapping past my tail pointer
recently.
But what the heck, yes please. I'm sure James will appreciate it ;)

Testing mainline would be useful.

I asked David Jones about it. He said he is in a push to get FC6 out
the door and there are more pressing TODO items.

Bad news,
I tested 2.6.18-git11 tonight. Both Network Manager and CPUFreq
(Speedstep) are busted here as well. I think I'll start trying
changing some build options to try to narrow it down.

Odd, it works for me here.
Hm, but that's not at boot time, I load the module at udev init time.
Miles, are you using this as a module or built into the kernel?
Hm, I'm also running it on a single proc machine, which really does not
show any race conditions in the pci probe logic very well.
Anyone have a dual-core laptop they want to donate to the effort? :)
thanks,
