There seem to be some problems with Suse 9.2, USB and AMD64-Sytems. I can't say if only Tyan-Motherboards have such problems but we had similar ones: we have a quad opteron (Tyan S4882) with 32GB RAM where it was not possible to install Suse 9.2 Prof because it hangs on USB-detection during DVD-boot. We switched back to Suse 9.1 wich installed proberly. But the system
You can disable USB detection with hwprobe=-usb
If you have a serial console you can also post the last messages before the hang.
freezes from time to time on high processor-load. We still don't know why ...
Try updating the BIOS and check the memory with memtest86.

The BIOS is as new as possible, I think from 28.01.2005. memtest had been running for a couple of hours but found nothing. I tried different boot-options for no acpi, iommu=force/noforce and played around with the BIOS options and so on but it still freezes. We also download SLES9 and installed it on a second hdd but the system freezes also. We watched some processes to be killed sometimes, so we have to cases: the system freezes or our test processes die suddenly. We test the system with one of our own binarization-program wich needs lots of RAM, vgstudiomax (also lots of RAM) or the 64bit-setiathome. I got a kernel oops only one time saying a process running at CPU3 tried to adress RAM of CPU0. I couldn't reproduce this oops but we are now checking the RAM-Modules. The system is currently running at 8GB (2G at each processor) for testing. We got 8GB of Infinion and 24GB of Samsung-Modules. Maybe mixed RAM don't work correctly somehow. Its stable now for a couple of hours. I rebuilded the smp-kernel without NUMA-support and it was stable for 8 hours or so. Normaly the systems freezes after a few minutes if all cpu's are fully loaded. Many Thanks, N. Eschricht
