[Bug 623325] [NEW] Number of CPUs in linux-generic-pae

[Christian Nygaard]

Public bug reported:

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
