 ### Known Issues
-* CTS may hang in VK.synchronization.internally_synchronized_objects.pipeline_cache_compute with Linux kernel versions lower than 4.13
-* The driver can only work with firmware of ME feature version >= 25 (you can check the version with command "sudo cat /sys/kernel/debug/dri/0/amdgpu_firmware_info"). If you are using upstream stack with GPUs of SI or CI family, you may need to upgrade the kernel to 4.19 or later version and firmware (under /lib/firmware/amdgpu/) to the right version from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu, and then update ramfs (sudo mkinitramfs -o /boot/initrd.img-\`uname -r\` \`uname -r\` **or** sudo mkinitcpio --generate /boot/initrd.img-\`uname -r\` \`uname -r\`)
+* If you are using upstream stack, you may need to upgrade the kernel to 5.3 or later version and firmware (under /lib/firmware/amdgpu/) to the right version from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu, and then update ramfs (sudo mkinitramfs -o /boot/initrd.img-`uname -r` `uname -r` or sudo mkinitcpio --generate /boot/initrd.img-`uname -r` `uname -r`)
 * Timeline semaphore is not fully supported in Linux kernel until version 5.5. You can install [Vulkan timeline semaphore layer](https://github.com/KhronosGroup/Vulkan-ExtensionLayer) to enable the extension if you are using earlier version of Linux kernel
