Package: firmware-amd-graphics Version: 20260810-1 Severity: important On a TUXEDO Stellaris 16 Gen7 AMD (Ryzen 9 9955HX3D, Raphael iGPU, PMFW 98.26.0) suspend to idle fails on nearly every attempt with firmware- amd-graphics 20260810-1: the iGPU SMU no longer responds on resume (amdgpu "SMU: No response msg_reg: b", resume of IP block <smu> failed -62), the display stays dead and only a hard reset helps. Reproducible with pm_test=devices, i.e. without platform sleep.
Replacing only the Raphael blobs (dcn_3_1_5_dmcub, psp_13_0_8_*, vcn_3_1_2, sdma_5_2_6, gc_10_3_6_*) with the versions from linux- firmware 20240318 fixes it on the same kernel (7.2.7.1); the system then reaches S0i3. Kernels 7.1.8, 7.1.10 and 7.2.7 are affected alike. Upstream report with logs and firmware versions: https://gitlab.freedesktop.org/drm/amd/-/issues/5962 This makes suspend unusable on affected Ryzen 9000HX laptops. Please consider holding back the affected files or adding a NEWS/known-issue entry until upstream has a fix.
