Hi, I have a dual opteron rig and can't install suse 9.1 on it. It hangs every time.. I've tried it with acpi on, without acpi.. without acpi and DMA, have turned all the powersave functions in bios off. It still doesn't work. I managed to install it once and during the installation I moved the mouse everytime. But it hangs every time when running KDE3. can't use YOU to update because of the crashing of the machine. Have run several memory tests.. installed Windows XP and ran prime95 for hours, 3d05 for hours. No problem no crashes.. This is my rig: Dual AMD Opteron 244 Tyan Tiger K8W 2 GB Corsair Low Latency pc3200 Registered ECC (4* 512 Mb) Leadtek Winfast A360 256 MB (Nvidia FX5700) 4 * WD 360GD (raptor 10.000 RPM) Plextor 116A DVD-rom drive 360 Watt Chieftec 02B-BX-BX case 2 *92mm intake coolers 1 * 120mm outlet cooler Suse Professional DVD install 64-bit /boot on a separate partition. / on md0 (linux soft raid 5) 4 swap partitions Need help!
