Hi Jianfeng,
Following commit 3d09a6e26d ("eal: fix threads block on barrier") I am seeing
testpmd crashes on startups.
The crashes occur 10% of the time with a regular compilation:
make install T=x86_64-native-linuxapp-gcc
and 70% of the time when using "-g" and "-o0" flags:
make install T=x86_64-native-linuxapp-gcc EXTRA_CFLAGS+=-g EXTRA_CFLAGS+=-O0
config/common_base:
CONFIG_RTE_LIBRTE_MLX4_PMD=y
I am running with an mlx4 Mellanox NIC on an Azure VM.
Please note the crash back trace in [1].
Have you witnessed similar reports?
I can provide more details if needed.
