由于电源故障（我的备用电池没有接住）而突然重新启动我的服务器后，我的电视调谐卡不再工作。不会/dev/dvb自动创建。多年来一切都运转良好。我最近没有更新，我使用的是 Debian 10 (buster)。

如果更新了新的内核映像，我总是会重新启动，所以我不相信我有一个替换内核的待处理更新，所以我不会认为新的内核映像放弃了对我的 ngene 固件的支持。
sudo modprobe lgdt330x并且sudo modprobe ngene什么也不做。然而尝试modprobe ngene_15报告：
sudo modprobe ngene_15
modprobe: FATAL: Module ngene_15 not found in directory /lib/modules/4.19.0-9-amd64
