in short: the bios is broken, it return wrong segment in DSDT. I *think* what Yinghai is saying is: - MMCONFIG is not used either in 2.6.26 or 2.6.32. - BIOS reports these host bridges via DSDT PNP0A08 devices: [PCI0] leading to segment bus 00 [PCI1] leading to segment

Hi Ralf, can you attach the complete dmesg log to the bug report, please? I see a snippet (starting with Bluetooth: SCO socket layer initialized), but there's a lot of useful information before that. The dmesg command only shows the most recent part of the log, so if the kernel's buffer has

Thanks! These tests: if ((dev-vendor == PCI_VENDOR_ID_AMD) || (dev-device == PCI_DEVICE_ID_AMD_GOLAM_7450)) are clearly wrong. I suspect was intended instead of ||, but this code seems to have been that way since the beginning, so I

Ralf, can you attach your /proc/iomem contents, too? I looked at the SP5100 TCO timer: mmio address 0xfec000f0 already in use message, but I don't see why that address is in use. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Your error is SP5100 TCO timer: mmio address 0xbafe00 already in use. (Same error, but different address.) That looks like it's in the middle of your RAM, i.e., it looks completely bogus. Given the ugliness of the sp5100_tco driver, that doesn't surprise me. Possibly the BIOS configured it
