map_user_kiobuf on 2.4.21-241 x86_64

Hi Andi, I mapped /dev/raw/raw1 to /dev/hda2 and wrote this simple problem, which hangs immediately, Is this also because of zero filled pages ? Just need a confirmation. I would really appreciate if you could pass me the bug no and access to bugzilla.suse.com. #include #include #include static char large_buffer[1024 * 1024]; void main () { int fd; fd = open ("/dev/raw/raw1", O_WRONLY); if (fd < 1 ) perror("failed to open him\n"); if (write(fd,large_buffer, sizeof(large_buffer))) printf("wrote something \n"); } Thx, Satish
