Hi Len, if you look through all the messages in this list, you could make this summary (IMO) 1. Freeze at different graphic cards (nvidia and ati) = wipes out propritrary drivers 2. Freeze with framebuffer = wipes out Xorg, as one option should be stable 3. Freeze with dual-core and single core = wipes out special kernel 4. Freeze on 32-bit and 64-bit =wipes ou tspecial system 5. Freeze on Ubuntu-Systems, too, and some Fedora-Core (someone mentioned that) = wipes out special Debian-problem 6. All ones report running kernel 2.6.18 or 2.6.17 = should wipe out kernel itself, except some modules did not change from one version to the other 7. It is a real bug, as it appears on all machines: notebooks and desktops 8. I myself tested the modules with kanotix (using memtest) and, checked ever bank single: No errors ! = wipes out hardware crash (additional would it be fany, when so much hardware would die suddenly) 9. I had some crashes, when I was on console, so I would have seen something abnormal. But nothing was seen ! Th emachine just stopped. Well, I hope, this would help a little to stalk to the bug.
