[regression: 2.6.25-rc6: iwl3945]

Hi,

I've been testing out the 2.6.25-rc kernel, and I've run into a possible
regression.

When I connect to my University's wireless network, I get the following
in my system logs
(This is just in one min. and it continues until I turn the computer off):

This didn't happen when I was using the 2.6.23 or 2.6.24 kernels. Also
it only _(or almost only)_ happens on the Uni. network. At home (where
the problem doesn't happen) my wireless router is a Hawking HWR54G. I
have no idea what the Uni. router is. On both, I connect to an
unencrypted network, but at the Uni. it redirects to a login page where
I have to log on before I can actually use the Internet. Also, even
though I get this flood of kernel messages, I can still use the Internet.

My network card is a Intel 3945ABG.

I was told by another developer (related to another regression I've
found) that the problem could be something about "pipe programming timing".
