commit 21f1ed489ec00b401cfd83b20ac7077fda7dc4e9 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Mon Feb 16 09:41:39 2015 +0200
AMD fam14: Blacklist Intel Centrino n6235 from PCIe ASPM
PCI device ID of this mini-PCI-e WLAN card is 8086:088e.
With this card inserted on pcengines/apu1 mini-PCI-e slot J17, system halts late in ramstage, in agesawrapper AMD_INIT_MID.
Offending operation is enabling PCIe ASPM L0s and L1 for the card. That is, writing PCIe capability block Link Control [1:0] = 11b in the card's configuration space. AGESA already has a blacklist for the purpose of masking such unstable ASPM implementations.
