Tony, Jesse, I have to wonder: why is it taken so long to get this
regression fixed? The regression was reported 69 days ago and the first
patches to fix this went out 40 days ago. That's far from ideal.

Reminder: this regression ideally should have been fixed within two
weeks after the report, as explained here:
https://docs.kernel.org/process/handling-regressions.html

FWIW, in case anyone wonders: the latest patch-series to fix this can be
found here:
https://lore.kernel.org/intel-wired-lan/1660310750-290943-1-git-send-email-grzegorz.siwik@intel.com/

Thx for working on it Grzegorz! Side note: might be good to add a
"Reported-by", but it's not really important I guess.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.

BTW, let me update the regzbot status:

#regzbot introduce: 5eda8afd6bcc
#regzbot poke
