Hello, I'm also still experiencing this issue on 5.1.15. It's making it very difficult to use my work laptop in my office, since it has many access points and frequently has to reauthenticate. I hit this bug 1-3 times per day, and the only way to fix it is a hard shutdown. Has there been any effort to identify and/or fix the cause? -- Skyler On Tue, 2019-06-25 at 15:03 +0200, Marc Haber wrote: > On Sun, Jun 02, 2019 at 03:48:42PM +0200, Marc Haber wrote: > > On Thu, May 30, 2019 at 10:12:57AM +0200, Marc Haber wrote: > > > on my primary notebook, a Lenovo X260, with an Intel Wireless > > > 8260 > > > (8086:24f3), running Debian unstable, I have started to see > > > network > > > hangs since upgrading to kernel 5.1.
