| |
Just tried shiny-new 2.6.27 kernel on this my system, with compiled-in ASPM support. And become curious by this message during bootup:
Pre-1.1 PCIe device detected, disable ASPM for 0000:00:06.0. It can be enabled forcedly with 'pcie_aspm=force' PCI: bridge 0000:00:06.0 32bit mmio: [fea00000, feafffff]
Here's the device in question:
00:06.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 2)
Should I be concerned by this presence of "Pre-1.1 PCIe device"? Which should not be Pre-1.1, I think...
And here's the system specs:
AMD 780G/SB700 based Asus M3A-H/HDMI motherboard, with AMD Phenom 9750 CPU. lspci:
