I tried on 12 computers and it didn't help. I'm updating BIOS on all computers since we have mostly first versions of BIOS that came with computers. I'm also disabling Intel Virtualisation Support in BIOS that some forums suggested.
This is really crazy. We had zero problems with freezing on Ubuntu 10.04, but since 12.04 it's happening all the time.
