The distro is Arch Linux, and a relevant log file is attached.

Can you try our core39 release, as explained in our wiki[1] and see if the problem still happens with that? We had a bunch of changes in the IRQ rx handler recently, so the problem may be solved in our internal tree already.

The issue does not happen (no "BUG" line or stack traces) on 4.14.72 but is reproducible on 4.18.11. 2. The issue also does not happen with the new core39 release and -41 firmware. 3. The "Unhandled alg: 0x707" line appears in all cases. Test method: Using 123456/123456 as username/password, and TTLS/MSCHAPv2 as the authentication mechanism for a WPA2-EAP Eduroam hotspot. In my case, the hotspot is provided by some Cisco device.

Fixed that in upstream backports, it'll take a while to propagate to backport-iwlwifi, but it eventually will. Thanks for the report!

I'll pull your fix into our core release soon, during my next round of merging back from upstream. The patch that fixes this "scheduling while atomic" issue is already in net-next.git[1] and should go to 4.20. When it reaches 4.20 it will be automatically backported to the relevant stable kernels. I could have sent it to the 4.19-rc series, but since it's not a regression in 4.19, I preferred to send it to -next instead.
