Reason for closing:  Upstream

I don't think there is a point in opening the bug report here, as with every single version of the 4965 ucode, someone's wireless breaks, there's at least three of these reports open and I cannot do the slightest thing about any of them.

@Thomas: These three bugs can be closed as "upstream"?, can do nothing with a blob driver. These bugs are already reported to upstream.

I am unsure what to do with them. No matter what we do, with the next ucode release more bugs will be opened, Intel can't seem to get 4965 right (the 3965 and 5xxx work better). I think we should close them, provided there is not a thing we can do.

EDIT: Some correction on your terminology: It is not a binary blob driver, the ucode is executed inside the wireless chip, not the host CPU. All code executed on the CPU is GPL.
