Hi,

I have encountered following problem while I was booting linux on armv7 noc.


./build/ARM/gem5.fast  configs/example/fs.py
--machine-type=VExpress_GEM5_V1 --kernel
/home/khilji/gem5/m5/system/binaries/vmlinux --disk-image
/home/khilji/gem5/m5/system/disks/linux-aarch32-ael.img --dtb-filename
/home/khilji/gem5/m5/system/dtb/armv7_gem5_v1_4cpu.dtb --num-cpus=4
--cpu-type=timing  --mem-size=512MB  --ruby --num-dirs=4 --garnet-network
flexible --topology Mesh --mesh-rows 2 --numa-high-bit=28

I am using Linuxv4.3 from git source and latest dtb from latest gem5 repo.
Any suggestions please. Why this thing appears and the booting process
almost stops

best regards,
sharjeel
