I recompiled the kernel but I also got those page faults. I asked on these newsgroups and people suggested the processor was broken. Then I tried config -r (well I didn't know the -r option so I did the equivalent - deleting the compile/XXX directory) and then it worked great. I think that config -r has to be done very occasionally. I guess when it has to be done, it is obvious.
