Description Dan Johansson 2019-12-13 09:03:10 UTC
After updating from sys-kernel/gentoo-sources-4.14.143 to 4.14.152 and later to 4.14.156 my Intel Dual Band Wireless AC 7260 does not work anymore.

Looking at dmesg after boot I see the following:

With 4.14.143 it looks like this:
[    9.250495] iwlwifi 0000:3d:00.0: enabling device (0000 -> 0002)
[    9.256063] iwlwifi 0000:3d:00.0: loaded firmware version 17.3216344376.0 op_mode iwlmvm

[    9.528596] iwlwifi 0000:3d:00.0 wlp61s0: renamed from wlan0


This is on a HP ZBook (as you can see in the above output).
And as I said it was working fine with 4.14.143.

Any suggestions?

Dan
Comment 1 Dan Johansson 2019-12-30 13:31:43 UTC
iwlwifi-7260-17.ucode does not help in this case.
The kernel > 4.14.143 still "crashes" when the iwlwifi module loads.
Comment 2 Dan Johansson 2020-01-31 14:48:31 UTC
After updating to sys-kernel/gentoo-sources-4.14.166 the problem has go away.
Everything is working as expected again.

Dan
