Same problem here. I have a Lenovo L570 laptop. Wifi is an Intel Corporation Wireless 8265 / 8275 (rev 78). Reverting the mentioned commit solved the problem. Please let me know if I could help by testing etc. CHL There is a comment on the LKMO who commited https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ce2e1ca703071723ca2dd94d492a5ab6d15050da where he explains that "sorry, my bad" is why WIFI is broken in kernel 5.6. He points out that this patch resolves the issue: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=be8c827f50a0bcd56361b31ada11dc0a3c2fd240 I have not tested that myself but I am guessing that the wifi broken in 5.6 and 5.6.1 issue can be resolved by applying be8c827f50a0bcd56361b31ada11dc0a3c2fd240 I'm running 5.6 with ce2e1ca703071723ca2dd94d492a5ab6d15050da reverted on two machines so I can say with certainty that WIFI works just fine with that solution. Note that 5.6.1 does not have any fix. Hello, same here. Device: 02:00.0 Class: Network controller Vendor: Intel Corporation Device: Wireless-AC 9260 SVendor: Intel Corporation SDevice: Wireless-AC 9260 Rev: 29 Driver: iwlwifi Module: iwlwifi As described above, reverting `ce2e1ca703071723ca2dd94d492a5ab6d15050da` solves the problem. ...or apply commit 7908d2658f92b5164d715959d51ebb88f4ad891b https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.6.y&id=7908d2658f92b5164d715959d51ebb88f4ad891b From https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.6.2 commit 7908d2658f92b5164d715959d51ebb88f4ad891b Author: Johannes Berg <johannes.berg@intel.com> Date: Sun Mar 29 22:50:06 2020 +0200 mac80211: fix authentication with iwlwifi/mvm commit be8c827f50a0bcd56361b31ada11dc0a3c2fd240 upstream. The original patch didn't copy the ieee80211_is_data() condition because on most drivers the management frames don't go through this path. However, they do on iwlwifi/mvm, so we do need to keep Changing the status of this bug to RESOLVED - PATCH_ALREADY_AVAILABLE as the release of 5.6.2 has the above cited patch. |
