Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: Disable MMIO access during SMU Mode 1 reset
During Mode 1 reset, the ASIC undergoes a reset cycle and becomes

during this window (e.g., from interrupt handlers or other driver threads)
can result in uncompleted PCIe transactions, leading to NMI panics or
