This email, part of this thread, https://lore.kernel.org/all/87r0kircdo.fsf@vps.thesusis.net/ clearly states that reverting *only* this commit, 56e449603f0ac5 drm/sched: Convert the GPU scheduler to variable number of= run-queues *does not* mitigate the failed suspend. (Furthermore, this commit doesn't= really change anything operational, other than using an allocated array, instead of a s= tatic one, in DRM, while the 2nd patch is solely contained within the amdgpu driver code.) Leaving us with only this change, b70438004a14f4 drm/amdgpu: move buffer funcs setting up a level to be at fault, as the kernel log attached in the linked email above show= s. The conclusion is that only b70438004a14f4 needs reverting. --=20 Regards, Luben --------------sNB7zEQc118Idxyi1MymNAMe Content-Type: application/pgp-keys; name="OpenPGP_0x4C15479431A334AF.asc" Content-Disposition: attachment; filename="OpenPGP_0x4C15479431A334AF.asc" Content-Description: OpenPGP public key Content-Transfer-Encoding: quoted-printable -----BEGIN PGP PUBLIC KEY BLOCK----- xjMEZTohOhYJKwYBBAHaRw8BAQdAWSq76k+GsENjDTMVCy9Vr4fAO9Rb57/bPT1A PnbnnRHNIkx1YmVuIFR1aWtvdiA8bHR1aWtvdjg5QGdtYWlsLmNvbT7CmQQTFgoA QRYhBJkj7+VmFO9beaAl10wVR5QxozSvBQJlOiE6AhsDBQkJZgGABQsJCAcCAiIC BhUKCQgLAgQWAgMBAh4HAheAAAoJEEwVR5QxozSvSm4BAOwCpX53DTQhE20FBGlT MqKCOQyJqlMcIQ9SO1qPWX1iAQCv3vfyJwktF7REl1yt7IU2Sye1qmQMfJxdt9JM bMNNBs44BGU6IToSCisGAQQBl1UBBQEBB0BT9wSPcCE8uGe7FWo8C+nTSyWPXKTx 9F0gpEnlqReRBwMBCAfCfgQYFgoAJhYhBJkj7+VmFO9beaAl10wVR5QxozSvBQJl OiE6AhsMBQkJZgGAAAoJEEwVR5QxozSvSsYA/2LIFjbxQ2ikbU5S0pKoaMDzO9eG z69uNhNWJcvIKJK6AQC9228Mqc1JeZMIyjYWr2HKYHi8S2q2/zHrSZwAWYYwDA=3D=3D =3DqCaZ -----END PGP PUBLIC KEY BLOCK----- --------------sNB7zEQc118Idxyi1MymNAMe-- --------------zdhIbyuVIrAPRu0RHztAccg6-- --------------B9KvWMDdbyeGAXg0IZipz9I3 Content-Type: application/pgp-signature; name="OpenPGP_signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="OpenPGP_signature.asc" -----BEGIN PGP SIGNATURE----- wnsEABYIACMWIQSZI+/lZhTvW3mgJddMFUeUMaM0rwUCZWbByQUDAAAAAAAKCRBMFUeUMaM0r6jz AP4zTPvRhz6Cv17QqsLz2rphQRnP0Y53BGjckIVgs/JMUAD/R/QYTr1qhzapp2VOHTym3teg3yR4 P0cKURfARvAUOw0= =1QtL -----END PGP SIGNATURE----- --------------B9KvWMDdbyeGAXg0IZipz9I3--
