Are you only experiencing this issue w/ a 2.6.34 kernel? Or also
with Fedora-provided kernels? If the latter, please be sure to open
a bug at bugzilla.redhat.com and Cc: linville(a)redhat.com when you do.

This looks like the firmware died. Since this is iwl3945, you might
try a patch like Reinette suggests here:

https://bugzilla.redhat.com/show_bug.cgi?id=589777#c5

Does that enable the device to recover?

This did not use to be an issue with 3945 and unfortunately we do not
know what is triggering it now. Please try the "Enable stuck queue
detection on 3945" patch that is attached to
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1834 as a
workaround.

Actually, sorry, but that patch will not work on 2.6.34 since the
feature it enables is not present there - it will be in 2.6.35 though.
To enable the feature in 2.6.34 will take some more backporting effort
that I'm looking into now.

I didn't have a problem with 2.6.34 but with 2.6.35-rc1 while obtaing IP
address with dhcpcd it bails out with reason 3 and gets timed out. I've
tried to increase timeout to 100 but the result is the same. I can't
apply this patches because base is somewhat different, as I can see the
first patch is already applied but the second one isn't. Any
suggestions ? Thanks. In the meantime I will try to get some more debug
information.
