No change:
LnkCtl: ASPM L0s L1 Enabled; RCB 64 bytes Disabled- Retrain- CommClk+
ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-
LnkCtl: ASPM L0s L1 Enabled; RCB 64 bytes Disabled- Retrain- CommClk+
ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-
Boot messages include:
[ 0.000000] PCIe ASPM is disabled
[ 2.132444] e1000e 0000:03:00.0: Disabling ASPM L0s
[ 2.293944] e1000e 0000:02:00.0: Disabling ASPM L0s
[ 8.489378] e1000e 0000:02:00.0: Disabling ASPM L1
(the latter is on the gigabit link).
Either lspci is lying to me, or the kernel's attempts to disable ASPM
are doing nothing at all.
I will find out soon enough which is true, as I'm no longer doing the
continuous pingflood, so if ASPM is on (or the problem is somewhere
else), the card will hang again...
