我的笔记本电脑中有以下以太网控制器
08:00.0 Ethernet controller: Qualcomm Atheros Killer E2500 Gigabit Ethernet Controller (rev 10)
journalctl -xe我的输出中不断出现这些警告
Nov 30 05:22:55 laptonix kernel: alx 0000:08:00.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID)

Nov 30 05:22:56 laptonix kernel: alx 0000:08:00.0: [ 6] BadTLP
上述消息不断发送，偶尔会出现错误消息，例如
Nov 30 05:23:15 laptonix kernel: i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe A (start=143095 end=143096) time 1792 us, min 1062, max 1079, scanline start 962, end 60
我在用Ubuntu 21.10与内核版本5.13.0-21-通用还在实时 USB 上使用 21.04 进行了测试，并得到了相同的消息。
我读过许多关于添加到内核启动pci=nomsi或的解决方案，pci=noaer但pcie_aspm=off这些对我都不起作用。
这是内核的一个错误吗？或者我能做些什么来阻止这些消息出现在日志中？
