tracing test causes kernel panic #1191

Closed chenguanxi12138 closed 1 week ago

chenguanxi12138 commented 1 week ago

I'm having a problem doing ftrace stress testing and can't pinpoint the cause Test Script:

#!/bin/bash

./stress_test2.sh &
sleep 5
./stress_test2.sh &
sleep 10
./stress_test2.sh &
sleep 15
./stress_test2.sh &
sleep 7
./stress_test2.sh &
sleep 15
./stress_test2.sh &
sleep 10
./stress_test2.sh &
sleep 5
./stress_test2.sh &
sleep 2h
stress2.sh
#! /bin/bash
for ((;;))
do
    ./runltp -f tracing
    ./testcases/bin/msgstress03 > /dev/null
done

System crash after running for a while
