[Resend because the mail client on my phone decided to turn HTML on behind my back, so my reply got bounced.] Thanks Thorsten. I did try to revert but it didnt revert cleanly and I don't have the knowledge to fix it up. The patch was part of a merge that included a number of related patches. Tomorrow, I'll try to revert the lot and report back. Chris On 27/01/2023 11:20, Linux kernel regression tracking (Thorsten Leemhuis) wrote: > Hi, this is your Linux kernel regression tracker.
