lspci hotplugged
Can you describe this issue please? For example, this is when device is connected preboot:
38:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller (2) I225-LMvP [8086:5502] (rev 03)
...
Capabilities: [a0] Express (v2) Endpoint, MSI 00
...
LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+
ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-
This is when device is hotplugged:
38:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller (2) I225-LMvP [8086:5502] (rev 03)
...
Capabilities: [a0] Express (v2) Endpoint, MSI 00
...
LnkCtl: ASPM Disabled; RCB 64 bytes, Disabled- CommClk+
ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-
ASPM should be enabled for hotplugged case, too.
