(e)udev에 의해 로드된 어떤 모듈이 시스템 정지를 일으키는지 어떻게 찾나요?

나는 두 개의 서로 다른 커널을 가지고 있습니다. 하나는 많은 장치 지원으로 구축되었고 다른 하나는 그다지 많은 장치 지원으로 구축되지 않았습니다. 장치 지원이 적은 장치는 구형 P5K Pro마더보드에서 제대로 부팅되는 반면, 장치 지원이 많은 장치는 전체 시스템을 중단시킵니다.

PS/2 키보드를 사용하고 로딩/트리거링(e)udevd를 건너뛰어야 합니다(이는 USB 키보드가 작동하지 않음을 의미함). 80-drivers.rules로드하지 않아도 중단되지 않도록 범위를 좁혀 보았습니다 (그러나 장치 지원은 없음). 파일 내용은 다음과 같습니다.

# do not edit this file, it will be overwritten on update

ACTION!="add", GOTO="drivers_end"

ENV{MODALIAS}=="?*", RUN{builtin}+="kmod load $env{MODALIAS}"

장치 지원이 적은 커널에서는 다음 장치가 표시됩니다.

udev(실제로는 eudev)를 실행하면 항상 중단됩니다.

시스템이 중단될 때 udev 디버깅 그림

어떤 모듈이 시스템을 정지시키고 있는지 확인하는 방법은 무엇입니까? (PS/2 키보드가 정지된 상태에서는 작동하지 않으며, 완전히 정지된 상태입니다.) 시스템이 재설정되는 경우도 있습니다(꺼졌다가 다시 켜짐).

티아! !
