18.04.1挂起并且系统间歇性冻结

所以我新安装的18.04.1系统间歇性地冻结了。 我试着查看kern.log和journalctl日志来查找崩溃中的模式，但我无法这样做。 当崩溃发生在8.35时，我正在附加kern.log。 日志显示ath10k_pci固件崩溃。 但我在以前的系统崩溃中找不到这些日志。

如果您需要其他日志，请告诉我。 或者你可以告诉我在系统再次冻结时收集所有相关日志的步骤。

我想我遇到了与此问题中提到的相同的问题： Ath10k和QCA6174导致PCIe错误，固件崩溃和连接丢失？

但是那里提供的解决方案无法应用于我的系统。 由于atheros github存储库没有我的固件版本WLAN.RM.4.4.1-00079-QCARMSWPZ-1的最新版本。 （注意结尾的Z）
