Re: WLAN broken on Nokia N900 with v6.2-rc1

For regression tracking only:

+CC regressions@lists.linux.dev

Issue is solved with a patch already on the way into mainline.
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20230111&id=4444bc2116aecdcde87dce80373540adc8bd478b

Issue was found and fixed independently of the regression report, so no 
regression tags in the commit.

Should have seen the potential sooner, but can you please check if the
following patch fixes the issue?

This patch seems to be a perfect fit to what you are describing...

Yes, someone pointed me to this patch a day ago, and it does fix the
issue indeed.

Apologies for not responding sooner.

That was fast:-)
Thanks for testing and reporting back.

FYI:
There is another regression report which has that as a very likely 
but not
yet confirmed fix:

(The discussion above has another patch you really want to have when 
AMPDU
is supported.)

I will give this a try as well during the course of the week. I noticed
the speeds were low, but that could just be the weak hardware itself
(1x600MHz ARM CPU), and I have not had time to compare performance from
before the commits in question.

Please keep me posted on the outcome. I expect no relevant change but 
then I did not test the patch on weak HW so far...
