Re: [iwlwifi] 6.3 regression, AX201 crash on traffic activity with Pixel 7, bisected

["Linux regression tracking (Thorsten Leemhuis)" <regressions@leemhuis.info>]

Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting
for once, to make this easily accessible to everyone.

This looks stalled.

Gregory, Evgeny afaics provided some of the data you asked for here:
https://bugzilla.kernel.org/show_bug.cgi?id=217419

But then afaics nothing happened anymore. Or was progress made and I
just missed it?

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

If I did something stupid, please tell me, as explained on that page.
