Operating system issues with Intel® dual-core processors (Hyper-Threading enabled)

Some versions of Microsoft® Windows® and distributions of Linux may hang during OS installation, fail to complete OS installation, or fail to boot after installation on servers with either three or four Intel® dual-core processors installed.

Action:

Microsoft® Windows Server™ 2003-based media

• System may hang during installation or during boot. Windows Server™ 2003 SP1 Slipstream does not exhibit this issue.
• If SP1 Slipstream media is not available, the base media installation can be performed using one of the following methods:
  • Install the OS with only one or two processor(s)
  • Disable Hyper-Threading in RBSU, then apply SP1 before adding the additional processor(s) and re-enabling Hyper-Threading

Linux distributions

• Additional information and the appropriate solutions for the Linux distributions (if any) can be found at the HP website.
