Hi,
I got the following erros while compiling a kernel for my 5000/240:
gcc -I /home/bunk/linux/include/asm/gcc -D__KERNEL__ -I/home/bunk/linux/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -G 0 -mno-abicalls -fno-pic -mcpu=r3000 -mips1 -pipe -c -o c-r3k.o c-r3k.c

While booting the kernel I had the same problem Flo already reported:
