> > We've tested using netdev tree and it is working. > Unfortunately, the fact that it works under the Linus tree and under the netdev-2.6 tree does not mean that the cause of the problem has gone. This is because the request_module calls from the DCCP tree are missing. So one could test by 1) trying the DCCP patch on the Linus tree http://eden-feed.erg.abdn.ac.uk/latest-dccp-test-tree.diff.gz 2) check netdev-2.6 + DCCP patches -- but you already tested this and it was the reason for this thread. Looking at your .config file again yesterday I noted that it sets # CONFIG_64BIT is not set CONFIG_X86_32=y # CONFIG_X86_64 is not set CONFIG_X86=y, i.e. you are compiling a 32 bit kernel on a 64bit (Athlon) processor. On the Sempron I use a 64 bit kernel and it works. Yesterday evening I tried (with some difficulties) to build the 32-bit variant and, ecce, after building it it hung in a call to request_modules for a binformat module. Hence I think that one likely cause may be a 32/64 bit issue. Did you notice any other module-related build problems on the 32 bit kernel? Earlier you mentioned that SCTP also was not working. There are other parts of the (networking) system that also call request_module, (grep -R request_module net/), for instance if TCP pluggable congestion control is built as a module -- I take it this is working correctly?
