usb에 fat32, ext2, ntfs 형식에 40만 2바이트 저장시 커널 패닉이 납니다..정말 해결방법이 없을까요?

콘솔로 프로그램 짠 소스입니다. usb에 폴더에 저장하는 프로그램입니다.
usb 형식에 fat32, ext2, ntfs 형식에 저장을 시도했습니다.
system call, system 함수등을 다 사용해 봤는데 18번째 부터 커널 패닉이 납니다.

커널 문제로 보고 있는데, 커널쪽에 어느쪽을 수정해야 할지 막막합니다. 아시는 분 꼭 답변 부탁드립니다.

int main(int argc, char **argv)
{
char message[11];
char m_sur[400002];
char path[30]="/mnt/concel/";
char test[2];
int fd;

fputs("input file:", stdout);
fgets(message, sizeof(message), stdin);
memcpy(path+12, message, sizeof(message));

int i, j;
for(i=0;i<1;i++)
{
for(j=0;j<10;j++)
{
path[17] = j + '0';
int fin;

fin = open(path, O_WRONLY | O_SYNC | O_CREAT, 0777);
if(fin != -1)
{
int a;
for(a=0;a<400000;i+=1024)
{
if(i+1024 < 400000)
write(fin, m_sur+a, 1024);
else
write(fin, m_sur+a, 400000-a);
usleep(100);
}

write(fin, test, 2);
close(fin);
usleep(1000);
}
}
}

return 0;
}

콘솔 테스트 프로그램입니다. 리눅스 피시에서는 당연히 잘 될구요..

18번째 저장할 때 커널 패닉이 납니다.
1~14번까지 저장 잘 하다가
attempt to access beyond end of device
sda1 : rw = 0, want = 67115554, limit = 522464
에러 화면이 나오구요...
3번더 저장이 되구
커널 패닉이 납니다....도대체 무슨 문제일가요?

커널에 버그이면 어떻게 해결해야 하나요?
