Does it _only_ hang during coredumping, or also during normal usage? Could you remove down_read(&mmap_sem); binfmt->coredump(); up_read(&mmap_sem); from fs/exec.c and rerun your tests? The hang during coredumping is known, there are 2 fixes [I have one, not yet released, Andrea wrote one, IIRC included in his -aa kernels]. Up to 2.4.10 there was a second hang with /proc/*/stats, that one is fixed in 2.4.10. -- Manfred - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
