Hi,

we've got a report about the regression with the latest iwlwifi 9260
*-46.ucode that landed recently in linux-firmware tree.  WiFi doesn't
work any longer on some Dell machines with that firmware.  See details
in:
  https://bugzilla.opensuse.org/show_bug.cgi?id=1142128

Currently we're reverting to the previously released firmware files.

Is it a known problem that has been already addressed?
If not, shall we revert the changes as a tentative workaround?


Thanks!

Takashi

Adding Dor.

Hi Takashi,

Do you have full logs of the crash? We can't see much from the log
snippet pasted in the bug report.

In any case, today or tomorrow, I'll release a new FW version for 9260,
hopefully it will solve the problem.  I'll send you a link so you can
test it when I push it to our tree (which feeds linux-firmware.git).

Thanks for reporting!

Luca.

OK, I'll ask reporters.  If you have a SUSE/openSUSE bugzilla account,
feel free to join there.

Good to hear.  I'll create a test package once when I have the new
firmware.


Thanks!

FYI, the dmesg's have been uploaded to the same bugzilla entry:
  https://bugzilla.opensuse.org/show_bug.cgi?id=1142128

Thanks!

BTW, I pushed new firmwares to our firmware tree in git.kernel.org
today.  This is the patch:

https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/commit/?id=b5f09bb4f816abace0227d0f4e749859364cef6b

It would be great if you can try it out and let us know whether the problem is gone or not.

I created a test package and asked for testing.
The test result seems negative, showing the same error,
unfortunately.

The dmesg was uploaded on the bugzilla entry.


HTH,

Hello Luca,

Any updated information on this iwlwifi-9260 firmware 46 issue?  Is 
there bug tracker or repo I should be looking to for following the 
progress on it?

Thanks Takashi! We will look into them as soon as possible (sorry for
the late reply, I just came back from vacations).

Actually, I just noticed that your bugzilla is closed as "RESOLVED
FIXED".  Is this still an issue?

This seems like a mismatch between the WiFi and BT firmwares... And
most likely the same issue as this:

It's "closed" because our package contains the revert.

OK, so we need the update of the whole linux-firmware.
I'll refresh the package and ask for testing.

I'm not sure the new BT firmware is in linux-firmware yet, since I
don't handle BT stuff.  I hope it is.

I just double-checked this and got confirmation that the latest BT
firmware in linux-firmware.git is compatible with the latest WiFi
firmware there as well.

The only caveat is that the machine needs to be cold-booted for it to
work....

But we are taking steps to make sure this will not happen next time
(i.e. for future hardware), by syncing our BT and WiFi firmware
releases.

Now we got a feedback from the latest linux-firmware (20190726) and
surprising the result was negative.  The dmesg after the cold boot is
found at:
  https://bugzilla.suse.com/show_bug.cgi?id=1142128#c26

The kernel is 5.2.3, so it should be new enough.

If anything else needed (or something missing), let us know.


thanks,

Takashi

I read on some forum that some commented that the "Add support for SAR 
South Korea limitation" fix is needed, but it seemed weird...

Anyway, with theese on top of 5.2.7

39bd984c203e86f3  iwlwifi: mvm: don't send GEO_TX_POWER_LIMIT on version 
< 41
f5a47fae6aa3eb06  iwlwifi: mvm: fix version check for GEO_TX_POWER_LIMIT 
support
0c3d7282233c7b02  iwlwifi: Add support for SAR South Korea limitation


We have confirmation from an affected user that its now stable with both 
older and newer firmwares...

And we earlier tried with only the:
39bd984c203e86f3  iwlwifi: mvm: don't send GEO_TX_POWER_LIMIT on version 
< 41

But that did not help (not that I really expected it since its loading 
version 46 firmwares anyway)

So my guess is that the newer firmware actually subtly expects to get 
the behaviour of the:
0c3d7282233c7b02  iwlwifi: Add support for SAR South Korea limitation



Of course that's still guessing and I assume only Intel fw guys can 
verify that...
