Unable to install FreeBSD-8.2-RELEASE

[mapcorp]

Hi,

I have a 4x Opteron 6172 server (48 cores) which I'm trying to install FreeBSD. It starts loading the kernel but hangs after detecting the CPUs (only detects 32 cores). What can I do?

Thanks

Try the latest 9-CURRENT shapshot from here:
http://ftp.freebsd.org/pub/FreeBSD/snapshots/201105/FreeBSD-9.0-CURRENT-201105-amd64-dvd1.iso

If that one will also hang, submit a BUG here:
http://freebsd.org/send-pr.html

... and post mail to the freebsd-current [AT] lists.freebsd.org and freebsd-stable [AT] lists.freebsd.org mailing lists with description of Your problem.

As Vermaden says I think FreeBSD 9 is for you:

Kernel & low level improvements
Large-scale SMP support

Status: Committed to -CURRENT
Will appear in 9.0: sure
Author: Atillio Rao and others
Web: commit message

This work brings in support for large SMP systems, with more than 32 CPUs. Previously, the kernel structures were unable to account for such a large number of CPUs so the newest method implements extensible CPU accounting. This is not an improvement in scalability in itself but is a prerequisite for large-scale SMP work.
