Linux regressions report for mainline [2022-05-15]

Linux regressions report for mainline [2022-05-15]

[Regzbot (on behalf of Thorsten Leemhuis)]

Hi Linus! Find below a quick compilation of open reports about
regressions in 5.18-rc that I'm currently aware of.

There is WIP for most of them:

* the "clk/bcm2835 breaking raspi" is report and patch at the same time
that is more that two weeks old, but seems the maintainer hasn't picked
it up yet :-/

* for the "input/usb problem with bcm5974" there is a rough but already
tested patch in bugzilla

* didn't look closely at the "mm: [mm/page_alloc]  f26b3fa046:
netperf.Throughput_Mbps -18.0% regression" thing, you were involved in
those discussions yourself

* for the "net: dpaa2" thing there is a patch in bugzilla that is
awaiting testing by the reporter

* for the intel graphics problem a patch was tested and discussed on the
list, but not yet heading towards you afaics

HTH, Ciao, Thorsten

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

Currently I'm aware of 30 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.

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/
