I'm aware that bios bugs are not related to FreeBSD. Machine we're speaking about is one of the official mirrors for FreeBSD in Bulgaria. System was running fine with HZ=2000 from 2005 to 2007 with a single CPU and 5-stable series. After I moved back to Sofia we moved it to 7-stable, 1000 HZ by default and added a second CPU. I'm trying to isolate the problem with the help of all subscribers - I don't have frequent access to the server room which leads to delayed troubleshooting. Will change CMOS battery and update bios as a start. Thanks for helping. Best regards, Dimitar Vassilev
