4.11-rc* iwlwifi instable

4.11-rc* iwlwifi instable

[Andi Kleen]

Hi,

Since I updated my laptop to 4.11-rc* the wireless is fairly instable
(I think it was already less stable with 4.10 than with 4.8, but no
clear data) 

For example it locked up (no more wireless) with a warn on while connecting
and actually needed a reboot to recover (reloading modules was not
enough)

Any fixes/workarounds?

Thanks,
-Andi

It seems that you are using an old firmware version:

> [70585.074356] iwlwifi 0000:03:00.0: Loaded firmware version: 21.302800.0

We have already published version -27 for 4.11 and you're still using
version -21.  You can get the latest version from here:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-7265D-27.ucode

We have loads of fixes and improvements in this new version.  And
hopefully it will make your problems go away. ;)

Please try it and let me know how it goes.

This is -27, but the driver looks for -28

It is expected to work with -21.  If it really doesn't work with it
anymore, but works with the newer ones, I'll bump the minimum supported
version so we'll print an error and bail out.

TL;DR: this error message is harmless and the driver tries to load -27
if -28 is not available.

Long story: We upstream driver patches from our internal tree constantly
and, at that point, we don't know which FW version will pass all the
quality gates to be released officially.  The driver in 4.11 supports up
to version -28.  We haven't release -28 yet, though (and maybe won't),
so you get this error message when we try to load it.  But if it fails
to load, we try to load the one immediately below it and so on, until we
reach the minimum API version we support.

These errors are definitely annoying and confusing, but I don't know how
to work around them.  Luckily Luis is working on the firmware class[1]
and part of his work will make these messages go away.

Hope this helps.  And please let me know if iwlwifi-7265D-27.ucode works
for you.

A warning may be better because it can be difficult to get a
new firmware if the network is dead. Or perhaps error + override
argument.

Even the old firmware works at least for some time.

So far it seems to work, and connects much faster than the old one.

Thanks,

Hopefully you keep the previously working kernel around when you try a
new -rc. ;)


> Even the old firmware works at least for some time.

Now seriously, as I said before, -21 is expected to work, but we don't
really do much testing with older firmwares after we released new ones. 
We already have two newer versions in linux-firmware.git[1], -22 and
-27.

I have checked it a bit further and I see that we even stopped
supporting firmwares older than -22 [2] (since 4.9-rc1).  But it seems
that I made a mistake in that patch and use -17 for all NICs, while it
should have been -17 for older NICs and -22 for newer ones... I'll send
a patch to fix that.

That's good to hear! Please let us know if you find any issues with it.
