Hi. I just got a Fujitsu Siemens Celsius V810 dual Opteron Workstation. It comes equipped with an Nvidia QuadroFX card but I am having trouble getting the machine to run properly under Linux. The problem is that the 8151 AGP tunnel can not be found and thus the graphics card can not be found. I have tried the Suse kernel (up to and including -178) as well as 2.6.1-X8664-2. Could this be a similar problem to the one that affected the Tyan Thunder K8W (S2885) a while back when the kernel could not find the 8151 AGP tunnel because of some PCI search issue. The board looks very similar to the Tyan 2885 both feature wise and by visual inspection but apparently it is not the same as on my 2885 everything is works as expected and the 8151 is identified correctly. Output from lspci is as follows and as you can see there is no 8151 in sight. 00:06.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8111 PCI (rev 07) 00:07.0 ISA bridge: Advanced Micro Devices [AMD] AMD-8111 LPC (rev 05) 00:07.1 IDE interface: Advanced Micro Devices [AMD] AMD-8111 IDE (rev 03) 00:07.3 Bridge: Advanced Micro Devices [AMD] AMD-8111 ACPI (rev 05) 00:07.5 Multimedia audio controller: Advanced Micro Devices [AMD] AMD-8111 AC97 Audio (rev 03) 00:0a.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8131 PCI-X Bridge (rev 12) 00:0a.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X APIC (rev 01) 00:0b.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8131 PCI-X Bridge (rev 12) 00:0b.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X APIC (rev 01) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:19.0 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:19.1 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:19.2 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:19.3 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 01:00.0 USB Controller: Advanced Micro Devices [AMD] AMD-8111 USB (rev 0b) 01:00.1 USB Controller: Advanced Micro Devices [AMD] AMD-8111 USB (rev 0b) 01:0b.0 Unknown mass storage controller: CMD Technology Inc: Unknown device 3114 (rev 02) 01:0c.0 FireWire (IEEE 1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link) 02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703 Gigabit Ethernet (rev 02) On my Tyan 2885 lspci find the 8151 as can be seen below. 00:06.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8111 PCI (rev 07) 00:07.0 ISA bridge: Advanced Micro Devices [AMD] AMD-8111 LPC (rev 05) 00:07.1 IDE interface: Advanced Micro Devices [AMD] AMD-8111 IDE (rev 03) 00:07.2 SMBus: Advanced Micro Devices [AMD] AMD-8111 SMBus 2.0 (rev 02) 00:07.3 Bridge: Advanced Micro Devices [AMD] AMD-8111 ACPI (rev 05) 00:07.5 Multimedia audio controller: Advanced Micro Devices [AMD] AMD-8111 AC97 Audio (rev 03) 00:0a.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8131 PCI-X Bridge (rev 12) 00:0a.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X APIC (rev 01) 00:0b.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8131 PCI-X Bridge (rev 12) 00:0b.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X APIC (rev 01) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 NorthBridge 02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703 Gigabit Ethernet (rev 02) 03:00.0 USB Controller: Advanced Micro Devices [AMD] AMD-8111 USB (rev 0b) 03:00.1 USB Controller: Advanced Micro Devices [AMD] AMD-8111 USB (rev 0b) 03:0c.0 FireWire (IEEE 1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link) 04:00.0 Host bridge: Advanced Micro Devices [AMD] AMD-8151 System Controller (rev 13) 04:01.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8151 AGP Bridge (rev 13) 05:00.0 VGA compatible controller: nVidia Corporation NV31 [GeForce FX 5600] (rev a1) Any ideas? /peter
