problem with modules

anyway, i believe the reason module loading is failing is because of the ramfs_nommu_mmap function being a stub (see linux-2.6.x/fs/ramfs/file-nommu.c)...

int ramfs_nommu_mmap(struct file *file, struct vm_area_struct *vma)
{
    return 0;
}

shouldn't this be setting vma->vm_start to something at least?

if your modules reside somewhere other than ramfs, everything seems to work ok. try loading your modules from a filesystem on a cf card or something...

I had the same problem when boa was serving files from ramfs using mmap. Looks like it is fixed in kernel version 2.6.18. ramfs_nommu_mmap now looks like this:

int ramfs_nommu_mmap(struct file *file, struct vm_area_struct *vma)
{
        return vma->vm_flags & VM_SHARED ? 0 : -ENOSYS;
}

I changed this in my kernel version 2.6.16 and now my boa problem was gone.
