No multiprozessor support for Sandybridge?

Hello all,

I use a Intel Core I5 2500K CPU 3.3 GHz 64-Bit system. Nightly build hrev 50878.

I don't get multiprocessor support! Only one Core is showing up.

Some time ago it was working... Do I have to turn it on somewhere?At boot maybe?

Ingo... (i think he is maintaining the multiprocessor support) has disabled it some time ago... is it on and running now?

Milestone: R1/beta1R1

Multi-processor is working fine for me and many others (including HyperThreading). It is enabled by default.

Please read the instructions on making a bug report: In particular:

  • Do not assign tickets to "beta1". It is up to the devs to decide what to include there.
  • Please include a syslog

Also make sure the problem isn't elsewhere, like maybe your BIOS has a setting for this? Does it work in other operating systems? Which version of Haiku are you running? x86_64? gcc2? gcc5?

I use Haiku hrev.50887 x86_32 gcc2 build. Booting from CD.

Running on Intel Core I5 2500K CPU 3.3 GHz 64-Bit system.(Maybe I have to try the Haiku 64Bit Version Gcc2?!

smp: using ACPI to detect MP configuration

smp_mp_probe: found floating pointer structure at 0x000fce40
smp: intel mp version 1.4, virtual wire compatibility mode.
smp: invalid config table signature, aborting

Could be a problem with ACPI probing? Is there a newer version of BIOS/UEFI for this mobo?

I tried the 64Bit (hrev 50908) Version without luck... ;-(
