[opensuse-factory] Random desktop lockups with kernel 5.9.x

Hi! Ever since my machine got upgraded to kernel 5.9.x, my Tumbleweed installation is randomly locking up (KDE, X11). Booting into the last 5.8.x kernel fixes the problem, so it's definitely related to the kernel and not anything else. Does anyone else see such lockups? This is on a Dell E7470 laptop with Intel Skylake graphics (Skylake GT2 [HD Graphics 520]), in case it might be related to bugs in the GPU driver. Adrian
