I thought that booting with the pcie_aspm=force option should make
sure this was enabled, but passing this to a 3.8.0 kernel, lspci still
shows:
LnkCap: Port #0, Speed 5GT/s, Width x16, ASPM L0s L1, Latency L0
<64ns, L1 <1us ClockPM- Surprise- LLActRep- BwNot-
LnkCtl: ASPM Disabled; RCB 64 bytes Disabled- Retrain- CommClk+
ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-
What could be disabling ASPM? dmesg confirms: [ 0.000000] PCIe
ASPM is forcibly enabled
