BL460c Gen9 with Linux 32-bit: only one core CPU detected

I would like to know if it is possible at all to run a Linux 32-bit on a BL460c Gen9 server. 

 

I installed 2 linux 32-bit distros: Debian 8.0.0 and Ubuntu 12.04.5, and on both of them, linux detected only 1 CPU core (by inspecting the contents of "/proc/cpuinfo"). 

 

Whereas with linux 64-bit (Ubuntu 12.04.5 and Debian 8.0.0), linux can detect ALL of the CPU cores (I could see 2 CPU with a total of 48 cores).

 

I am wondering if there is a special kernel configuration that should be adjusted so that all CPU cores can be detected in 32-bit linux.


Many thanks in advance.

Only 64 bit OS's are supported on Gen9.  If you really must run a 32 bit OS, you can run it as a virtual machine.

Hello,

 

I finally solved the puzzle.

I have to DISABLE these two options at the same time:

  • ACPI SLIT Preferences
  • x2APIC Support

Disabling only one option will *not* do the trick.

Hope this helps for others.

It may work, but it has not benn tested, nor is it supported by HP or any Linux distributions
