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",

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...

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-

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?

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.

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

If the "capa flags index 3" message is not causing any problems, I
would ignore it as well.

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.

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.
