It says (kgdb) print cpu_ticks $1 = (cpu_tick_f *) 0x8077d340 This means that kernel is using tsc discipline actually imho.

Also HZ were 2000 instead of 1000, but at that time machine was a uniprocessor one. HZ=1000 by default, so are you saying you set it to 2000?

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.
