Linux regressions report for mainline [2024-03-03]

["Regzbot (on behalf of Thorsten Leemhuis)" <regressions@leemhuis.info>]

Hi Linus, things are mostly normal. Sadly normal as so often means that
fixes for some regressions are out there, just not yet in mainline.

 * A fix for "MXSFB error: -ENODEV: Cannot connect bridge"(*) appeared
in next-20240226 as d2f8795d9e50aa ("ARM: dts: imx7: remove DSI port
endpoints").
https://lore.kernel.org/lkml/34yzygh3mbwpqr2re7nxmhyxy3s7qmqy4vhxvoyxnoguktriur@z66m7gvpqlia/

 * A fix for "sc7180 lazor: Image corruption regression for DP"(*)
appeared in next-20240227 as 0d7dfc79fb9b4b ("drm/msm/a6xx: specify UBWC
config for sc7180".
https://lore.kernel.org/regressions/85581fad-da8f-4550
a1c8-8f2996425dcd@lausen.nl/

 * A fix for warnings during suspend from a misc driver from Hans is
waiting for a review since 12 days.
https://lore.kernel.org/lkml/5fc6da74-af0a-4aac-b4d5-a000b39a63a5@molgen.mpg.de/
https://lore.kernel.org/lkml/20240220190035.53402-1-hdegoede@redhat.com/

A few other things of note:

 * A lockdep splat in the stmmac code is not really making progress,
will prod tomorrow:
https://lore.kernel.org/lkml/ea1567d9-ce66-45e6-8168-ac40a47d1821@roeck-us.net/

 * Johan Hovold meanwhile continues a quest to fix various regressions
that affect the Lenovo ThinkPad X13s; some of the fixes have already
reached you, some are still under discussion.

 * The list still includes the "decreased network outgoing performance
due to IRQ sharing that happened after a xhci change" I brought up a few
days ago; I'll remove that from the tracking, as you didn't reply.
Likewise for the 6.7 regression "user can't set the minimum power limit
of their Radeon graphic cards as low as before". For details, see:
https://lore.kernel.org/all/f2eaf931-8488-48e3-b008-1cedeba24f12@leemhuis.info/

 * There are a kexec and a nouveau regression from this cycle that are
brand new.

Ciao, Thorsten

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

Currently I'm aware of 8 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.:
