Linux regressions report for mainline [2023-05-14]

Linux regressions report for mainline [2023-05-14]

[Regzbot (on behalf of Thorsten Leemhuis)]

Hi Linus. Sorry, I'm a bit behind with staying on top wrt to regressions
in recent cycles. But for 6.4 there is nothing much to report afaics.
Yes, there are a few regressions on my radar (see below), but most as of
now are business as usual (except the iwlwifi one, but I'll poke that
tomorrow) and not noteworthy.

One of the exceptions is a slightly urgent s2idle regression for amd
family 19h model 78h cpus[1], but you already have a pull request from
Boris in your inbox with the fixes.

What I can't see yet though is a pull request from Russell with a fix
from Ard[2] (in next as 2b951b0efbaa) for boot issues[3] that apparently
break a lot of arm32 configs, which among others lead to "tons of
different boot time errors on the syzbot arm32 qemu instance"[4]. That
sounds like someone that might be worth fixing rather sooner than later,
but maybe the patch is already on the way to you and I just missed it.

Hi, this is regzbot, the Linux kernel regression tracking bot.

Currently I'm aware of 9 regressions in linux-mainline. Find the
current status below and the latest on the web:

Bye bye, hope to see you soon for the next report.

=============
End of report
=============

All regressions marked '[ *NEW* ]' were added since the previous report,
which can be found here:

Thanks for your attention, have a nice day!

  Regzbot, your hard working Linux kernel regression tracking robot


P.S.: Wanna know more about regzbot or how to use it to track regressions
for your subsystem? Then check out the getting started guide or the
reference documentation:

https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md
https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md

The short version: if you see a regression report you want to see
tracked, just send a reply to the report where you Cc
regressions@lists.linux.dev with a line like this:

#regzbot introduced: v5.13..v5.14-rc1

If you want to fix a tracked regression, just do what is expected
anyway: add a 'Link:' tag with the url to the report, e.g.:

Link: https://lore.kernel.org/all/30th.anniversary.repost@klaava.Helsinki.FI/

I have that. You may not have seen it because rmk just cc's the ARM SoC list.

We also have some vhost regressions due to the move to user worker
threads (rather than kthreads), they don't seem to be on your list.
They're being worked on.

Ahh, yeah, that's why I missed it. Good that it made it, will set up lei
to not miss such pulls in the future.

Yeah, funny story, I seem to share the name with someone that joined the
discussion yesterday, as he also ran into a problem with that stuff. He
even uses my own private domain for his email address, too. I bet that's
the guy with strange hair that often looks me in the eye first thing in
the morning when I see this silver thingy on the wall. I'll have a word
with him to ensure he from now on will add his regressions to the
tracking himself. ;)
