Hello, Today I found the source of the problem. When I deactivate the second CPU core in the BIOS of the notebook, then I can start and use Haiku Alpha 2. By the way, I have the same problem with the newest nightly build. Please note that I tried all options in the safe mode and I deactivated the power management, the LAN, the wireless functions and almost anything that I could find in the BIOS configuration and the Haiku safe boot menu. Nothing helped. Only when I deactivate the second CPU core, then Haiku Alpha 2 runs, even when all the other features are activated. Why is this so? The Haiku Alpha 1 version runs wonderful on this notebook, even with both CPU cores. What was changes between Alpha 1 and Alpha 2 that could cause such a problem?
