My machine with an Ivy Bridge CPU is stable under Windows 7 but freezes in Ubuntu 12.04 LTS 64-bit. The freezing appears to occur randomly. I read somewhere that kernel 3.3.6 fixes the Ubuntu freeze issue. Any idea when this will be available in 12.04?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I had the same problem with a Gigabyte GA-H77-D3h Motherboard and an i5-3570 CPU. Freezing occurred on both, the 32-bit and 64-bit Versions of Ubuntu 12.04 LTS. Updating the kernel to 3.4.0 fixed this issue for me. The system has run without any crashes for several days know.

Same problem with my CPU (i7 Ivy Bridge 3770).

Try using kernel versions or before.

I had the same issue with a 3770 on an ASUS P8Z77-M. The most recent BIOS update fixed the problem after the most recent kernel did not.
