Thanks Ali. Now I have used config_arm_2.6.38_mp_fb to get a kernel build 2.6.38.
I can run my build in simulator with m5term monitoring the process. But the system got stuck after 5 seconds. Here is the last portion of the trace: [ 0.000000] [<c002e8ac>] (__dabt_svc+0x4c/0x60) from [<c02397bc>] (pcpu_dump_alloc_info+0x2c/0x298) [ 0.000000] [<c02397bc>] (pcpu_dump_alloc_info+0x2c/0x298) from [<c001152c>] (pcpu_setup_first_chunk+0x48c/0x7b0) [ 0.000000] [<c001152c>] (pcpu_setup_first_chunk+0x48c/0x7b0) from [<c0011ec4>] (pcpu_embed_first_chunk+0x674/0x734) [ 0.000000] [<c0011ec4>] (pcpu_embed_first_chunk+0x674/0x734) from [<c0011fb0>] (setup_per_cpu_areas+0x2c/0xb4) [ 0.000000] [<c0011fb0>] (setup_per_cpu_areas+0x2c/0xb4) from [<c00088d4>] (start_kernel+0xec/0x294) [ 0.000000] [<c00088d4>] (start_kernel+0xec/0x294) from [<00008034>] (0x8034) [ 0.000000] Code: e8b30003 e0222862 e58d200c e1d330b0 (e5870000) [ 0.000000] Unhandled fault: alignment exception (0x801) at 0xc02e84e6 [ 0.000000] Internal error: : 801 [#10] SMP [ 0.000000] last sysfs file: [ 0.000000] Modules linked in: [ 0.000000] CPU: 0 Tainted: G D (2.6.38-gem5 #1) Any idea on the alignment exception? Here is my gcc version: arm-linux-gnueabi-gcc -v ... gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-1ubuntu1) . The command I used to compile Linux is simple: make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- vmlinux -j4 Thanks for help.
