Yeah, that's one of those controllers I think. But I can't tell from the bit of the dmesg you posted exactly what's going on. Can you post a full boot log from having the card installed and some drive attached (by putting the boot drive on another controller for example)? >> ==> Further issues with the X9SRL-F -- does this board support ASPM or is >> this a Linux/ASPM implementation issue? >> [ 0.632170] pci0000:ff: ACPI _OSC support notification failed, > disabling >> PCIe ASPM >> [ 0.632239] pci0000:ff: Unable to request _OSC control (_OSC support >> mask: 0x08) > > What's the full dmesg from this machine (or is it already posted somewhere)? > > It is now available here: > http://home.comcast.net/~jpiszcz/20121128/dmesg.txt Is that the same boot log? It doesn't have this error in it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
