It does say that, yes.

I don't have any other iwlwifi adapters, so I wouldn't know. The people in
that Ubuntu bugreport have exactly that card as well, but in another notebook.
And they claim it works in newer Ubuntu, but I am running latest kernels with
latest uCode, so I'm out of ideas what else could be wrong.

Yeah, but considering how few people report this, I'm starting to feel that it
might in fact be a hardware issue. It is unfortunate that the wifi adapter in
this Lenovo model isn't placed in that part of the notebook on the back where
it could be easily replaced. If that was the case, I could easily swap it with
my colleagues without voiding the warranty.

(We've got a lot of Lenovos here, mostly T520 and T420s, most of them running
Fedora, and nobody has reported memory corruption problems. Mine is T420.
Perhaps I should try to connect to this WPA Enterprise using Windows and see
if anything goes wrong. However, I have no clue as to what shall I do to
reproduce the issue in Windows.)
