Hi all, It seems like using the kernel version x86_64-vmlinux-2.6.22.9.smp may have solved my problem that was posted in this thread: http://www.mail-archive.com/gem5-users@gem5.org/msg10387.html However, I am using the latest gem5 version gem5-stable-aaf017eaad7d and I only tested the atomic cpu without any checkpointing or fast forwarding. Are the any problems related to using an older kernel version (such as x86_64-vmlinux-2.6.22.9.smp) with gem5?
