Description Ian Kumlien 2020-03-30 10:41:58 UTC

Upgrading to 5.6.0 leaves my work laptop without wifi, there seems to be three tries and a timeout - it never manages to connect.

It's a: HP EliteBook 840 G5

With:
01:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

Other laptop with a different driver works fine though...

Sorry, this works ok with 5.5.13 - but not with with 5.6

Ok so this is known:

I can confirm the issue.

The particular commit in the changeset that causes the problem is ce2e1ca703071723ca2dd94d492a5ab6d15050da "[PATCH] mac80211: Check port authorization in the ieee80211_tx_dequeue() case", and reverting it fixes the issue for me.

Applying the fix linked from that Phoronix article should be a better solution though.
