Can you send me more details of your setup as I am quite experienced with UML and now completely stuck with AMD64. > Is your RAM OK? Oh yes, this has nothing to do with the hardware. > Which kernels do you have inside and outside? Host (outside): 2.6.19.2-skas3-v8.2 Inside: pick any of those (none of them work with >=2.6.16): http://uml.nagafix.co.uk/ > How are > you trying to build the 32-bit UMLs? These are the same as on the site above (which I maintain) and these have worked flawlessly for a long long time. I have downgraded the x86 boxes to 2.6.15.7 and these are up and running again. But I can't do that for all of them, and this is just not an option for some of the amd64 boxes. Thanks Antoine ------------------------------------------------------------------------- Take Surveys.
