PM_TRACE를 사용하여 램 중단 문제 디버깅

그래서 저는 털이 많은 메모리 중단 문제를 디버깅하고 있었는데,

이런 일이 발생하면 더 이상 시스템을 깨울 수 없습니다. 나는 커널 범위가 3.16 - 4.7인 데비안과 우분투에서 이것을 실행했습니다. 내 현재 커널은

Linux arjundesktop 4.7.6 #1 SMP Sat Oct 8 13:00:22 MDT 2016 x86_64 GNU/Linux

나는주의를 기울여 왔습니다.디버깅 일시 중지에 대한 기본 가이드. 내 dmesg 로그가 표시됩니다.

이 매직넘버는 무엇을 의미하나요? 내 tty에서 충돌이 발생했다고 말하는 이유는 무엇입니까? 내가 달릴 때

cat /sys/power/pm_trace_dev_match

알겠어요

usb
tty

무슨 뜻이에요? 어떻게 진행하나요? 산출lsusb
