Hi, this is your Linux kernel regression tracker.

Hmm, nothing happened here for a week. :-/ That's not how this should be
when it comes to regressions...

Jason, any news on this? A answer to Greg's question ("Does this also
have problems in the latest 5.15 and 5.19 release)") would be helpful.
Also: when your wrote "Running [...] a bisected kernel with commit
6d17a112e9a63ff6a5edffd1676b99e0ffbcd269 removed, [...]" I assume you
tested this with 5.10.y?

Side note: Sure, a bisection can easily got wrong, as Bart outlined. But
you also wrote "Running [...] a bisected kernel with commit
6d17a112e9a63ff6a5edffd1676b99e0ffbcd269 removed, [...]" sounds a lot
like the bisection didn't go sideways. Are you sure you nothing went
wrong when you tested this revert?

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.
