Christian Nygaard, thank you for reporting this and helping make Ubuntu better. As of Trusty this would still be 8: git clone git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git && grep -r CONFIG_NR_CPUS= | grep i386 debian.master/config/i386/config.common.i386:CONFIG_NR_CPUS=8
I'll mark this Triaged for now, so this request could be further reviewed. As well, could you please provide a full detail on why you are making this request? Is this just a general "it would be nice..." or would you have a requirement in your environment for PAE, that migrating to amd64 would be too onerous? Despite this, from the perspective of just one data point, if one is utilizing 8+ cores, then it may be best to switch to the amd64 version of the kernel for performance reasons -> http://www.phoronix.com/scan.php?page=article&item=ubuntu_x86_1304&num=1 . ** Changed in: linux (Ubuntu) Importance: Undecided => Wishlist ** Changed in: linux (Ubuntu) Status: Confirmed => Triaged ** Summary changed: - Number of CPUs in linux-generic-pae + Request increase CONFG_NR_CPUS= higher than 8 for linux-generic-pae ** Tags removed: needs-upstream-testing ** Tags added: trusty -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/623325 Title: Request increase CONFG_NR_CPUS= higher than 8 for linux-generic-pae Status in “linux” package in Ubuntu: Triaged Bug description: Binary package hint: linux-generic-pae In linux-generic-pae 32-bit kernel the config parameter CONFIG_NR_CPUS=8 is set to 8 this is to little for modern multicore CPUs. Suggestion is that this parameter is set to either 32 or 64. CONFIG_NR_CPUS=64 is the value used in the 64-bit kernel. Steps to reproduce: $ grep CONFIG_NR_CPUS /boot/config-2.6.32-24-generic-pae ./linux-2.6.32/debian.master/config/i386/config.flavour.generic-pae uname -a output: Linux ubuntu 2.6.32-24-generic-pae #39-Ubuntu SMP Wed Jul 28 07:39:26 UTC 2010 i686 GNU/Linux ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: linux-generic-pae 2.6.32.24.25 Regression: No Reproducible: Yes ProcVersionSignature: Ubuntu 2.6.32-24.39-generic-pae 2.6.32.15+drm33.5 Uname: Linux 2.6.32-24-generic-pae i686 AlsaDevices: Error: command ['ls', '-l', '/dev/snd/'] failed with exit code 2: ls: cannot access /dev/snd/: No such file or directory AplayDevices: aplay: device_list:223: no soundcards found...
