Details

Description:

Got an error using the latest kernel with my intel 7260 wifi Card firmware. Excluded an error inside the firmware. Error Code -5.
Reverted back to 4.7 Kernel using the --nodeps flag because nvidia driver complained and it worked again.

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:
Just try wifi on a 7260 wifi card with the latest kernel... doesn't work.
This task depends upon

4.8 gained support for newer firmware versions. To make 4.8 use the same firmware as 4.7 you can simply delete the firmware file, kernel will load the older version instead then.

Do you have any log with the faulty firmware?
Comment by Tobias Kornmayer (t0b1as) - Sunday, 23 October 2016, 17:48 GMT
Actually not, I would need to upgrade the kernel again to replicate. Would this be necessary? I could do so. Anyway, I do not suspect the firmware but the kernel since it works with the older one.
Comment by Tobias Kornmayer (t0b1as) - Sunday, 23 October 2016, 17:48 GMT
(the older kernel I mean, not any other firmware)

Well I have an Intel 7260 wifi card, I have had no trouble whatsoever with the 4.8.x kernels.

I got an error with Broadcom card. Maybe it's the same problem. Had to revert to 4.8.1, does this version work for you? You can get any package version from https://archive.archlinux.org/packages/l/linux/.
This kernel works with newest Nvidia, while 1.7 not.

Okay, sorry guys: it's an 8260 card:


lspci -k
6e:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)
Subsystem: Intel Corporation Dual Band Wireless-AC 8260
Kernel driver in use: iwlwifi

I replicated the error. Here's the dmesg output as it should be:

using kernel 4.7.6-1:
