Re: HELP! Mysterious oops around PIPE code, kernel 2.4.18

Yes, even with these modules removed it still would crash.

One mistake, my gcc version is actually 3.2.2:
gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

I'm really suspecting the code it has compiled, objdump -S gives
almost no dissasembly line in pipe_wait, and with only -d, it gives
lots nop at the end of the function. see below:

pipe.o: file format elf32-i386
