In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fixes a random hang in S4 for SMU v13.0.4/11 While doing multiple S4 stress tests, GC/RLC/PMFW get into an invalid state resulting into hard hangs. Adding a GFX reset as workaround just before sending the MP1_UNLOAD message avoids this failure.
