Hi Johannes and Amit, pointing to the RX path was a good idea! I checked the commits of the last three weeks and discovered that it turns out that the patches from Amit caused the regression: iwlwifi: add testmode command for rx forwarding http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=0aef8ddc8bedac1db4c96fddc9fb1b44b730cf4f iwlwifi: fixed testmode notifications length http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=8e81f65fdc7f5d292bb3c115b748767d921823c1 I reverted them in the opposite order (of course) and now the issue is gone.
