The problem is the smart battery support that was merged shortly after 6.0-RELEASE. Running wmbsdbatt the system freezes for 0.5s every 10s or so, this is because wmbsdbatt is polling for the battery status. Disabling wmbsdbatt everything was back to normal. This can also be reproduced here with a acpiconf -i loop. Other sources say, it's the thermal stuff thats blocking the OS, but for me it's battery status.
