I run Fedora Core 6 on the 'compaq nc6320' laptop. I am using the '2.6.19.1' kernel. While booting the kernel, I noticed the following 3 messages: 1. PCI: BIOS Bug: MCFG area at f8000000 is not E820-reserved PCI: Not using MMCONFIG. After some search, I commented out the 'e820_all_mapped()' check in the 'pci_mmcfg_init()' function. I no longer see this message and MMCONFIG method seems to be used now. But, is it the correct thing to do? I get these messages with '2.6.18.x' kernels as well. 2. synaptics reset failed For this, I commented out the following retry loop in the 'synaptics_query_hardware()' function as suggested on the synaptics driver website.. while ((retries++ < 3) && psmouse_reset(psmouse)) printk(KERN_ERR "synaptics reset failed\n"); Is this still the right thing to do? 3. usb 1-1: device not accepting address 2, error -71 I don't know what to do with this. There was a comment by someone that this is the problem of 'ehci-hcd' driver trying to access the usb controller while the 'uhci-hcd' driver is still working on it. My interest in this is that I am having troubles with 'suspend to disk' on this machine ( with both 'swsusp' and 'software suspend 2'). The suspension itself is not successful. I was wondering if any of these messages (especially the 'usb' one) are related to the suspend problem that I have. I have attached the 'lspci -v' output. This is a dual core laptop with the SATA drive. Thanks, --Vasu
