5.4.0-77-通用模块 e1000e 抱怨硬件错误

昨天我更新了我的 lubuntu 20.04，它附带了一个新内核。我今天启动它并得到

dmesg | grep -i hard
[    0.040601] Booting paravirtualized kernel on bare hardware
[    7.514435] e1000e 0000:00:19.0 0000:00:19.0 (uninitialized): Hardware Error
[   10.261171] systemd[1]: Condition check resulted in Rebuild Hardware Database being skipped.
[   14.944977] e1000e 0000:00:19.0 eth0: Hardware Error

因此我在 dmesg 中搜索之前使用 linux-image-5.4.0-74-generic 启动的情况

grep -i hard /var/log/dmesg.0
[    0.039776] kernel: Booting paravirtualized kernel on bare hardware
[    4.091866] systemd[1]: Condition check resulted in Rebuild Hardware Database being skipped.

我找到了启动选项

pcie_aspm=off

但这不会停用所有 pci 设备的 Active State Power Management 吗？还是我错了？我看看

modinfo e1000e | fgrep parm
parm:           debug:Debug level (0=none,...,16=all) (int)
parm:           copybreak:Maximum size of packet that is copied to a new buffer on receive (uint)

parm:           CrcStripping:Enable CRC Stripping, disable if your BMC needs the CRC (array of int)

是否有可能停用我的以太网卡的电源管理？

注意，我不知道卡在这种状态下是否可以工作（这里没有路由器）。

答案1

请尝试使用 pcie_aspm=off 内核参数启动内核。
