Yes, that's what happened. > I'd suggest to run a few rounds of memtest86, to > be sure it isn't a memory problem. Very good idea! I will do that. Why didn't I think of that myself??? I was too sure that the memory was ok after the BIOS has done its checks during POST... > Assuming that memtest doesn't find any memory > errors: > what hardware is persent in that machine and what > drivers > are used? Well, the hardware list can be found in my first posting. In case I have missed some important part, please let me know. I will be happy to give you all information that is needed. However, about the drivers: how can I find that out? I am not familiar with the kernel debugger. Is there a way to step through the booting process to see which drivers are loaded? > Could there be a problem with one of the > drivers and 64-bit DMA? > (Note that in the initial setup with 2*2GB of ram a > small part > of it probably was remapped to addresses >= 4GB; now > with > 8*4GB a lot of memory is >= 4GB) That sounds very plausible! However, can you tell me how to find the answer to that question? I will test it a.s.a.p. then... Phew, I really hope I'm (we're) getting somewhere here. Actually, I have to say that I'm currently writing this message by using a Ubuntu 9.04 LiveCD on this machine. So far everything runs smoothly. Maybe not a hardware problem? I hope so, because being a software engineer I'm more confident debugging code rather than hardware... ;-) Thanks again, everyone! I will post the results of the memtest as soon as I ran a few of them... Manfred -- This message posted from opensolaris.org
