Initially I was running inside VMWare. Which is that inside VMWare I run 
QEMU, in which I run RTEMS. The problem was there. Then I tried outside 
of VMWare on the same machine and the problem was still there, but the 
machine might have been under heavy load - I did it because I expected 
timer issues in VMWare, so I didn't check the load.

After reading your comment I run outside of VMWare and with no other 
load, and it worked...
