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. -Andi

The BIOS is as new as possible, I think from 28.01.2005. memtest had been

If you have the "memory hoisting" or "memory remapping" or similar option in the BIOS enabled try to disable it. If that doesn't help see below.

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.

This sounds very much like a memory or other hardware problem (especially the rebuilding without NUMA helps bit - this just changed the memory access patterns). Unfortunately memtest86 cannot catch them all because it only runs on a single CPU and also doesn't do any IO load. When memory is unstable installation can randomly hang too. I would contact your hardware vendor. -Andi

So, if I might hijack my thread back again, is there no way to install 9.2 on my machine that has happily been running 9.1 for about 9 months? Last November I successfully downloaded, burnt, and ran, the 9.2 Live DVD and so assumed the upgrade would work.

The 64->32bit upgrade probably has broken the installation severly. You can try to rescue something, but it might be a lot of work or not work. I would boot from the rescue system if possible and then save your data that you still need on an different partition, then do a reinstall with a format of the old root partition. Regarding why the DVD install did not work - that's very weird. What happens when you try to read the DVD e.g. from the rescue system. Can the DVD ROM read it properly then? The 9.2 DVD is double layer, maybe your DVD ROM doesn't like that. -Andi

My data isn't a problem I have it backed up.

The DVD looks OK when mounted in 386 Ubuntu, which I have on a separate partition.

The DVD boots OK and the installer starts to run. It activates the USB system and then hangs after "Searching for info file .... " which it presumably can't find.

Hmm, do you have more than 3GB of RAM? If yes try booting with mem=2G

What is this info file? The installer obviously can't find it.

That's one of the first files the installer tries to read from the DVD. It means it has some trouble accessing it at all. -Andi

Did you try to boot with "hwprobe=-usb" (from DVD)? I also have K8T Master2 far with 2GB - it installs fine. (I enabled all USB features) My BIOS (from dmidecode:) BIOS Information Vendor: Phoenix Technologies, LTD Version: 6.00 PG Release Date: 04/30/2004
