Subject: Linux regressions report for mainline [2024-05-05]

Hi Linus, here is the weekly report for regressions introduced during
this cycle. Most issues are either brand new, being worked on or likely
to be fixed during the next week. The latter might be the case for one
issue I want to highlight nevertheless:

* Ben Greear more than a month ago reported a reproducible hang during
startup and bisected it to the main merge window LED merge[1]. Ben
recently even submitted a iwlwifi patch to work around the underlying
problem[2]. But real debugging and patch review are making slow progress
afaics, so I'm not really sure if the issue will be resolved somehow
before 6.9 is out, which is why I wanted to quickly mention it.

Side note: I wonder if this issue is related to some other interactions
problems between the LED and net code that were fixed this cycle[3], but
Johannes thinks that is unlikely.

and c04d1b9ecce565 ("igc: Fix LED-related deadlock on driver unbind") [v6.9-rc6]


* FWIW, my plan was to bring up the -next regression fix
6677196fb1932e ("clk: qcom: gdsc: treat optional supplies as optional")
[next-20240404 (pending-fixes)] here too, which after more than a month
in -next is still not mainlined. But Stephen sent a PR on Friday[1], so
that might be resolved already when you see this mail.

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
[email protected] 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.:
