I'm getting a build error with gcc 4.6.0 and binutils 2.21: [...] AS arch/mips/kernel/entry.o AS arch/mips/kernel/genex.o /home/ralf/src/linux/upstream-linus/arch/mips/kernel/genex.S: Assembler messages: /home/ralf/src/linux/upstream-linus/arch/mips/kernel/genex.S:524: Internal error! Assertion failure in append_insn at ../../gas/config/tc-mips.c line 2867. Please report this bug. make[4]: *** [arch/mips/kernel/genex.o] Error 1 make[3]: *** [arch/mips/kernel] Error 2 make[2]: *** [arch/mips] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 make: Leaving directory `/home/ralf/src/linux/obj/nlm_xlr-build' Not sure what's blowin up there and I haven't had a chance to try other binutils versions yet. Is this something known? None of the other MIPS kernel defconfigs is encountering this issue. Ralf
