Yes, As it happens I have exactly the same kernel - fixdeps is in the kernel build scripts at /usr/src/linux-2.6.17-5mdv/scripts/basic/fixdep.c and a cursory examination would suggest that it shouldn't (modulo the compiler behaviour) be doing any floating point operations at all. On the other hand I can't reproduce the fault either, but this could be down to e.g. the architecture or something (I have X86_64 build here) /J\ > ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
