I found that the problem is caused by generic_file_aio_write function. I did quick patch with disable usage of generic_file_aio_write function and use only write function which works. I haven't debug generic_file_aio_write function. I am running Linux with initramfs and LTP programs are run from nfs. Have you ever met with this problem?
