Control: found -1 5.14.6-2 I have just tried installing the kernel from unstable. After reboot, the booting process just hung at the very early stage. Nothing was printed onto the screen, and I cannot find the logs, as it happened during booting from initramfs.
The problem may be specific to Debian, as I tried booting openSUSE Tumbleweed from LiveUSB with kernel 5.14.5, and it worked fine. I am using Lenovo Thinkpad E495 with AMD Ryzen 5 3500U CPU. -- Alexander Kernozhitsky
