Hi, this is your Linux kernel regression tracker. @kernel developers: you might want to consider ignoring this, the reporter provided additional information in the ticket and it looks a lot like it's not a regression. For details see: https://bugzilla.kernel.org/show_bug.cgi?id=215906#c4 Sorry for the noise.
