I'm running an Odroid-X2 as headless 24/7 server. With plain stable 5.10.1 I had 54 up days without problems. With opp-shared removed on kernels before and now on 5.11 my system freezes after some days on disk activity to eMMC (rsync, apt upgrade). The spontaneous hangs are not easy to reproduce but testing this for several months now I am quite confident that there is something wrong with this patch.
