[参考译文] TLV320AIC3254：TLV32x4驱动程序导致的内核错误和引导故障

https://e2e.ti.com/support/audio-group/audio/f/audio-forum/1268784/tlv320aic3254-kernel-errors-and-boot-failures-due-to-tlv32x4-driver

您好！  

我们正在我们的某个产品中使用您的编解码器、并已使用提供的 Linux 驱动程序成功将其集成到 Ubuntu 22.04.3中。 但是、驱动程序中存在一个错误、导致出现"原子调度"以及尝试写入不存在的存储器等错误。 由于客户的要求、我们无法自行选择使用自定义内核来修补驱动程序。 我们可以采取其他任何步骤来解决此问题、还是必须等待补丁？ 导致引导问题。  

当我们禁用驱动程序(这将禁用我们的音频功能)时、引导问题将消失。  

以下是我收集的有关此问题的一些日志：
