This is common problem of open_error_pipe ().

/* Creates a pipe to hold standard error for a later analysis. */
/* The pipe can hold 4096 bytes. Make sure no more is written */
/* or a deadlock might occur. */
void open_error_pipe (void)

So I will comment out all of open_error_pipe() and close_error_pipe () 
in the extfs.c and possible sfs.c.
