Hi, The 2.6.28.4 configuration file is the one that you need to properly build the kernel version 3.4.112. At least worked for me.
In order to enable SMP features you must edit the configuration before building, the easiest way is through menuconfig: https://en.m.wikipedia.org/wiki/Menuconfig Best, Cano.

So where can I download the other .config for gem5's kernel ? and how can I enable smp feature and specify the maximum amount of cores in the file .config ? -----原始邮件----- *发件人:*"Javier Cano Cano" <javier.cano...@gmail.com> *发送时间:*2017-03-23 23:31:03 (星期四) *收件人:* "gem5 users mailing list" <gem5-users@gem5.org> *抄送:* *主题:* Re: [gem5-users] run gem5 in FS mode with this kernel, though, I get this error: Kernel panic - not syncing: Attempted to kill the idle task! Hi, If you want to upgrade your kernel, use the 3.4.112 version and the provided .config. Just make sure to enable smp feature and specify the maximum amount of cores if you want to run multi-core simulations.
