Thanks for having whipped up this patch! Feel free to submit upstream to Linus, and also to Greg for inclusion in 5.15.y. Tested-By: Kris Karas In reply to Thorsten in comment 4, I did indeed test against 5.15.13 and 5.16-rc8 without success. This makes me curious... ... I filed this bug nearly 2 months ago with the "Regression =3D Y" metada= ta clearly set; but the various kernel regression trackers haven't picked up on that fact until just days ago. Are automated regression trackers only look= ing at messages on LKML? What's the best way to get a bugzilla report for a regression tracked so that it doesn't get forgotten or lost in the shuffle?= =20 For example, bug 199533 was filed back in 2018, with a proper bisect even, = but hasn't garnered even so much as a single comment. (Probably ought to be cl= osed as I no longer have the hardware to test a fix :-) Kris --=20 You may reply to this email to add a comment.
