Public bug reported: In the 32bit version of Ubuntu's linux-server package (or the kernel packages it depends upon) NR_CPUS is limited to 8 CPUs and BIGSMP is disabled.
Nowadays this restriction to 8 CPU cores is imho a bit outdated. We had to compile the kernel and reconfigure BIGSMP and NR_CPUS to make it work with 16 Cores. ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/940150 Title: Xubuntu Oneiric does not support more than 8 CPU Cores To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/940150/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
