What it likely means to say is that your kernel caused a segmentation fault. Check the output of 'dmesg'. If it says something like 'Nv Xid 13' (from memory, may be wrong--the 13 is what says 'segfault', I think), then that's what it is. Have you tried chopping your kernel down to almost-nothing? Bisected? HTH, Andreas
