Subject: Linux regressions report for mainline [2024-01-28]
Hi Linus. Nothing much to report from my side. Here are a few things I
nevertheless want to point out wrt. to regression from this or the
previous cycle:
* As already mentioned last week: quite a few people reported problems
that among others "break 32bit processes on x86_64 (at least). In
particular, 32bit kernel or firefox builds in our build system" (quote
from Jiri). The mm fix for that is in -next since Tuesday (currently as
0d0498b139768f ("mm: mmap: map MAP_STACK to VM_NOHUGEPAGE")), but sadly
not yet on the way to you (at least afaics):
https://lore.kernel.org/all/20240126075612.87780C433F1@smtp.kernel.org/
For details and problems reports see:
https://lore.kernel.org/linux-mm/d0a136a0-4a31-46bc-adf4-2db109a61672@kernel.org/
https://lore.kernel.org/linux-mm/CAJuCfpHXLdQy1a2B6xN2d7quTYwg2OoZseYPZTRpU0eHHKD-sQ@mail.gmail.com/
https://lore.kernel.org/all/1e8f5ac7-54ce-433a-ae53-81522b2320e1@arm.com/
https://lore.kernel.org/all/a914c7f2-cf9f-44a8-99d4-c25a66d39f1c@arm.com/
* There have been multiple reports that the keyboard on the popular
Dell XPS 13 9350 / 9360 / 9370 models on 6.7 has stopped working after
suspend/resume -- and the culprit that causes it recently sadly was
backported to a few stable/longterm series. Hans posted a fix on Friday
and asked sending them your way "ASAP", but that afaics has not happened
yet (no wonder given the timing):
https://lore.kernel.org/all/20240126160724.13278-1-hdegoede@redhat.com/
* Speaking of popular Linus laptops, in case anyone cares: GPIO is
broken on the Thinkpad T14s Gen1 AMD, a fix for it was posted on
Tuesday, sadly was not yet picked up afaics:
https://lore.kernel.org/lkml/20240123180818.3994-1-mario.limonciello@amd.com/
* Ohh, and the Apple M1 is plagued by boot failures, a fix for it is in
next as b40fed13870045 ("nvmem: include bit index in cell sysfs file
name") and also found here:
https://lore.kernel.org/all/20240122153442.7250-1-arnd@kernel.org/
Ciao, Thorsten

Hi, this is regzbot, the Linux kernel regression tracking bot.
Currently I'm aware of 6 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@...ts.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/
