Hallo,
beim Umstellen auf Xubuntu 18.04 (System 2) stelle ich fest, dass beim Entladen der Module der TT Budget S2-3200 es Probleme gibt. Beim Entladen des Modules stb0899 gibt es folgende Fehlermeldung im Kernel und das System wird instabil:

derzeitiger Workaround: Module nicht entladen. Allerdings bleiben dennoch einige Zweifel zwecks Stabilität.
