yesterday I updatet my lubuntu 20.04 that shipps a new kernel. I bootete it today up and get
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
So I search in dmesg for previous boot with linux-image-5.4.0-74-generic
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.
relevant hardware detail

I found bootoption
pcie_aspm=off
But would this not deactivate Active State Power Management for all pci devices? Or I'm wrong? I take a look in
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: WriteProtectNVM:Write-protect NVM [WARNING: disabling this can lead to corrupted NVM] (array of int)
parm: CrcStripping:Enable CRC Stripping, disable if your BMC needs the CRC (array of int)
Is there a possibility to deactivate power management for my ethercard there?
Note I have no idea if the card is in this state works (no router here). .
Please try booting the kernel with the pcie_aspm=off kernel parameter.
