Incomplete
Bug description:
This issue is 100% reproducible. It looks like this has something to
do with the Disco kernel in proposed (5.0.0-1014.14).
Test combinations:
kernel in updates + source code master branch = OK
kernel in proposed + source code master-next branch = NOT OK
kernel in proposed + source code master branch = NOT OK
The system will crash and reboot itself when testing:
"Register/unregister many kprobe events"
[33] Kprobe event with comm arguments [PASS]
[34] Kprobe event string type argument [PASS]
[35] Kprobe event symbol argument [PASS]
[36] Kprobe event argument syntax [PASS]
[37] Kprobes event arguments with types [PASS]
[38] Kprobe event auto/manual naming [PASS]
[39] Kprobe dynamic event with function tracer [PASS]
[40] Kretprobe dynamic event with arguments [PASS]
[41] Kretprobe dynamic event with maxactive [PASS]
[42] Register/unregister many kprobe events
packet_write_wait: Connection to 35.233.208.253 port 22: Broken pipe
