Hi, this is your Linux kernel regression tracker. Top-posting for once,
to make this easy accessible to everyone.

Luca, can you help me out please? Below regression was reported a while
ago in https://bugzilla.kernel.org/show_bug.cgi?id=215523

Goan about two weeks ago came up with a rough patch that helped:
https://bugzilla.kernel.org/show_bug.cgi?id=215523#c13

What the status of that fix? I couldn't find a similar fix in the
archives and no commit that linked to the ticket. I already asked Goan
for a update in the ticket about a week ago, but I didn't get an answer.

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

P.S.: As the Linux kernel's regression tracker I'm getting a lot of
reports on my table. I can only look briefly into most of them and lack
knowledge about most of the areas they concern. I thus unfortunately
will sometimes get things wrong or miss something important. I hope
that's not the case here; if you think it is, don't hesitate to tell me
in a public reply, it's in everyone's interest to set the public record
straight.

Hi, this is your Linux kernel regression tracker speaking.

There is a regression in bugzilla.kernel.org I'd like to add to the
tracking:
