I have no problems with the -current, but, as I've said, I have tuned speed down. If I remember correctly they running slower than their nominal speed. Dmesg shows 1380.01MHz, although they're 1800+. This is tuneable in the BIOS. harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.fraunhofer.de, harti@freebsd.org
