Hi Naresh,
the configuration is based on aspeed_g5_defconfig (see attached configuration file)
and the following qemu command line (qemu v5.2):
qemu-system-arm -M romulus-bmc -kernel \
arch/arm/boot/zImage -no-reboot \
-initrd rootfs-armv5.cpio -nic user -nodefaults \
--append "panic=-1 slub_debug=FZPUA rdinit=/sbin/init console=ttyS4,115200 earlycon=uart8250,mmio32,0x1e784000,115200n8" \
-dtb arch/arm/boot/dts/aspeed-bmc-opp-romulus.dtb \
-nographic -monitor null -serial stdio
It also happens with other bmc platforms using the same network interface, though
it is for some reason more prevalent on romulus-bmc.
The root file system is generated with buildroot. See buildone.sh / buildall.sh
in branch local-2021.02 of git@xxxxxxxxxx:groeck/buildroot.git. The warning happens
with almost every boot; the crash in maybe one of 5-10 boots. The test, if you want
to call it that, uses udhcpc to get an IP address and then
net_test_successful=0
ifconfig eth0 2>/dev/null | grep -q "inet addr:10.0.2.15"
if [ $? -eq 0 ]; then
ping -q -c 1 -s 1000 -W 1 -I eth0 10.0.2.2 >/dev/null
if [ $? -eq 0 ]; then
telnet 10.0.2.2:22 </dev/null >/dev/null 2>dev/null
if [ $? -eq 0 ]; then
net_test_successful=1

See package/busybox/run.sh in the above repository/branch.
