After upgrading the Raspi today I got flooded with the above error messages coming from kernel.

RPi3 or RPi4? -- You are receiving this mail because: You are on the CC list for the bug.

Hi Sid, this seems to be a separate issue, could you open another bug report.

If I look at the description of the bug: [RPi3] alloc_contig_range: [17800, 179c7) PFNs busy it looks exactly the same. Can you explain? -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1163582 http://bugzilla.opensuse.org/show_bug.cgi?id=1163582#c7 --- Comment #7 from Patrik Jakobsson --- Normally the "PFN Busy" message is not a problem and It's been discussed before at [1]. Are you sure you didn't have them before the upgrade? Perhaps something changed that triggers them more often or your memory usage is higher than before. OTOH the warning might be something to look closer at. [1] https://lore.kernel.org/patchwork/patch/746357/ -- You are receiving this mail because: You are on the CC list for the bug.

Perhaps you have enabled 3D acceleration with the Mesa-dri-vc4 package (not the xf86-video-fbturbo package)? Using the Mesa driver will allocate/deallocate much more memory and produce many more of these warnings.

Yes, the Mesa-dri-vc4 is enabled. So you recommend to disable the driver in order to get rid of the warnings? -- You are receiving this mail because: You are on the CC list for the bug.
