Hello,
Allow me to ask you the following question:
I have laptop with: "02:00.0 Network controller: Intel Corporation
Wireless 7265 (rev 59)".
For this device I found firmware iwlwifi-7265-ucode-25.30.14.0.tgz.
My problem is following: This firmware was created for kernel 4.2+, but
I am using
Centos 7 with kernels a la 3.10. Therefore I see during booting and
after switch off some
problematic messages a la:
capa flags index 3 larger than supported by driver or
failed to remove key (2, ff:ff:ff:ff:ff:ff) from hardware ...
Wi-fi works properly, not to look on the previous messages.
My question to you: do you have in schedule to include proper firmware
also for
centos 7/redhat 7?
Regards,
Dusan

If your kernel were newer, I would recommend running the backports drivers, but
I think 3.10 is too old. That said, this code change would not fix the "failed
to remove key" message as I get that on my 7260 device with kernel 4.16.0. I
think you may safely ignore this one if for no other reason than it only happens
when the device is being shut down.
If the "capa flags index 3" message is not causing any problems, I would ignore
it as well.

Wireless stack and drivers are regularly updated in Centos kernel,
(for example latest release has wireless drivers from 4.14)
and should match firmware provided in the distribution.

backports works for 3.10 and higher kernels so you are just on the good
side of it.

The log shows that the "divide error" occurs in your (proprietary)
nvidia driver. There is no relation to the wifi "issues" discussed in
this thread.

On this and most mailing lists, one should not top post. It is most inconvenient
to have to continually scroll up and down to get to your comments while writing
mine.
In your first posting, you said "Wi-fi works properly". That certainly does not
imply any problems other than the strange messages in the log. If you are
getting BUG and/or WARNING dumps, then the output of the dmesg command will list
the traceback. I do not see any of those. They may be a consequence of using
such an old kernel. I am only an Intel wifi user, not a developer, and it is
unlikely that I will be able to fix any of your problems. In any case, you need
to post the full tracebacks of those BUGS/WARNINGS here. Remember, do not post
at the top.
Larry
A: Because it puts things out of order.
Q: Why is top posting bad?
Dear Larry,
Thank you for your mail. But concerning to "capa flags index 3", I am
not sure. Please look
following message receiving for command "ps aux",
/usr/bin/abrt-watch-log -F BUG: WARNING: at WARNING:
CPU: INFO: possible recursive locking detected ernel BUG at list_del
corruption list_add corruption do_IRQ: stack over
flow: ear stack overflow (cur: eneral protection fault nable to handle

I am not software expert, but also looking on message from abrt:
Subject: [abrt] : divide error: 0000 [#1] SMP => look attachment.
Maybe it is direct consequence connected with my wi-fi problem...

Dusan
