RTEMS_FATAL_SOURCE_EXCEPTION during startup

[Петр Борисенко]

I didn't print anything explisitly.
Here is call stack:
```
Thread #1 (Suspended : Signal : SIGINT:Interrupt)
output_char() at console-config.c:104 0x8007132
rtems_putc() at rtems_putc.c:31 0x800f038

vprintk() at vprintk.c:31 0x8009aa0
printk() at printk.c:40 0x800794e
