Hi I tried this. I was able to build a new vmlinux image with the kernel configuration provided in the tarball. However, I had to set some of the configuration options manually to No while running make on the kernel source. I hope this is fine. I ran GEM5 with the newly built vmlinux image and it booted fine until it showed a kernel panic at one place : 2248908940000: system.cpu.break_event: break event panic triggered The output on M5term might be helpful in diagnosing the issue: VFS: Cannot open root device "sda1" or unknown-block(8,1) [ 0.003904] VFS: Cannot open root device "sda1" or unknown-block(8,1) Please append a correct "root=" boot option; here are the available partitions: [ 0.003904] Please append a correct "root=" boot option; here are the available partitions: 0800 5320248 sda[ 0.003904] 0800 5320248 sda driver: sd driver: sd <0>Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1) [ 0.003904] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1) [<c003440c>] (unwind_backtrace+0x0/0xd0) from [<c02dca50>] (panic+0x3c/0x118) [ 0.003904] [<c003440c>] (unwind_backtrace+0x0/0xd0) from [<c02dca50>] (panic+0x3c/0x118) [<c02dca50>] (panic+0x3c/0x118) from [<c0009190>] (mount_block_root+0x1c8/0x208) [ 0.003904] [<c02dca50>] (panic+0x3c/0x118) from [<c0009190>] (mount_block_root+0x1c8/0x208) [<c0009190>] (mount_block_root+0x1c8/0x208) from [<c00093ec>] (prepare_namespace+0x12c/0x180) [ 0.003904] [<c0009190>] (mount_block_root+0x1c8/0x208) from [<c00093ec>] (prepare_namespace+0x12c/0x180) [<c00093ec>] (prepare_namespace+0x12c/0x180) from [<c000872c>] (kernel_init+0x198/0x1e8) [ 0.003904] [<c00093ec>] (prepare_namespace+0x12c/0x180) from [<c000872c>] (kernel_init+0x198/0x1e8) [<c000872c>] (kernel_init+0x198/0x1e8) from [<c002ece0>] (kernel_thread_exit+0x0/0x8) [ 0.003904] [<c000872c>] (kernel_init+0x198/0x1e8) from [<c002ece0>] (kernel_thread_exit+0x0/0x8) This probably has something to do with the file system or the disk drivers ??
