Hello team, There seems to be patch available, but not part of upstream kernel source yet (checked against 4.18.7 git), provided by AMD employee. Applied the patch listed from page below to 4.18.6 kernel from kernel.org and no issues visible related to udev stuck as reported before. https://lore.kernel.org/patchwork/patch/974869/ (https://lore.kernel.org/patchwork/patch/974869/) BRTL
