+From: Ben Hutchings <ben@decadent.org.uk>
+Subject: iwlwifi: Do not request unreleased firmware for IWL6000
+Bug-Debian: https://bugs.debian.org/689416
+Forwarded: not-needed
+
+The iwlwifi driver currently supports firmware API versions 4-6 for
+these devices. It will request the file for the latest supported
+version and then fall back to earlier versions. However, the latest
+version that has actually been released is 4, so we expect the
+requests for versions 6 and then 5 to fail.
+
+The installer appears to report any failed request, and it is probably
+not easy to detect that this particular failure is harmless. So stop
+requesting the unreleased firmware.
