This happens always in this machine. I cannot replicate it in other machines I tested, e.g.: - Manjaro Linux (Intel Atom 330) - Linux Mint 15 (Intel Pentium T2330) - Fedora 19 (older Pentium M) - ARM boards + Manjaro Linux (Intel Atom 330) + Linux Mint 15 (Intel Pentium T2330) + Fedora 19 (older Pentium M) + ARM boards I attach a reduced testcase.
