This happens randomly once in several days. Often several seconds before it happens, network stop working. Then the system freezes and there is nothing I can do about it. It doesn't react even to SysRq magic keyboard shortcuts. I have to hard reset the PC. In systemctl -b -1 I can see the kernel oops (in attachment). Hardware is Lenovo Thinkpad T14 gen2 AMD (AMD Ryzen 7 PRO 5850U). I wanted to report it to kernel.org bugzilla, but is says to report to the distribution bug tracker first.
