Hello

1. No, I not installed ccache previously. Thank you by your hint.

2. Yes. I'm using a external USB hard disk (Seagate, 500 GB auto 
powered).  /usr/obj /usr/ports and /usr/src is mounted there.

3. No. I will do it also.

Unhappily I was using a NODEBUG kernel and no hint about the deadlock 
was printed. Maybe the deadlock can be caused by the micro SD HC card 
used but I can not affirm.

I give another try and this time I got a kernel panic at
