저는 Linux 커널 전문가는 아니지만 이 새 노트북을 구입했는데 WiFi(RT3290LE)가 작동하지 않습니다. 다양한 소스의 솔루션을 시도했지만 작동하지 않습니다. 그래서 그것을 알아내는 것은 나에게 달려 있습니다. 나는 이전에 커널 코드를 디버깅한 적이 없습니다. 그래서 그게 다입니다.
저는 커널 4.3.3-2-ARCH를 사용하여 Arch Linux를 실행하고 있습니다. 모듈을 로드할 때(다음에서 로드합니다.우레아 소변 비율또는에서우분투에 물어보세요), 다음은 dmesg에 나타나는 첫 번째 줄입니다.
[ 40.077355] rt3290sta: module license 'unspecified' taints kernel.
[ 40.077359] Disabling lock debugging due to kernel taint
[ 40.079739] register rt2860
처음 두 줄은 단지 경고일 뿐인데 왜 rt2860을 "등록"하는지 알고 싶습니다. 다음 몇 줄:
[ 40.079912]
=== pAd = ffffc90001c61000, size = 583104 ===
[ 40.079922] <-- RTMPAllocTxRxRingMemory, Status=0
[ 40.079958] <-- RTMPAllocAdapterBlock, Status=0
RTMPAllocTxRxRingMemory이 모듈에 대해 함수 및 RTMPAllocAdapterBlock가 정의되어 있기 때문에 rt2860 모듈이 로드 중임을 나타냅니다 . chipssrc 디렉토리에 .txt 파일이라는 디렉토리가 있기 때문에 이 모듈이 내 3290LE 칩도 처리할 수 있을 것으로 추측됩니다 rt3290.c. 거기에서 다음까지 모든 것이 괜찮아 보입니다.

NetworkManager로 분할 오류가 보고되었습니다. 그 시점부터 모든 것이 잘못되는 것처럼 보였습니다.

이는 RTMPReadParametersHook()(src/os/linux/rt_profile.c의 96행)에 있는 다음 코드에 의해 인쇄됩니다.
retval =RtmpOSFileRead(srcf, buffer, MAX_INI_BUFFER_SIZE);
if (retval > 0)
{
RTMPSetProfileParameters(pAd, buffer);
retval = NDIS_STATUS_SUCCESS;
}
else
DBGPRINT(RT_DEBUG_ERROR, ("Read file \"%s\" failed(errCode=%d)!\n", src, retval));
아래 주어진 함수는 -1을 반환하기 때문입니다.

모듈 로딩의 최종 결과는 전체 시스템이 불안정해지는 것입니다. 온라인에 접속할 수 없고 sudo 작업과 관련된 명령도 없으며 Ctrl-C/Z를 통해 중지할 수 없으며 DE 충돌이 발생합니다. 시스템을 종료하는 데에도 시간이 오래 걸립니다.
이 문제를 해결하고 WiFi를 작동시키려면 어떻게 해야 합니까?
질문이 너무 길어서 죄송합니다. 어떤 도움이라도 주시면 대단히 감사하겠습니다. 와이파이 없이는 못 살아요! :-(

업데이트 2:NetworkManager 충돌에 대한 버그 보고서를 제출했습니다.여기. 거기에서 제안한 대로 디버그 기호를 사용하여 NetworkManager를 다시 설치하고 추적을 시도했습니다. 그래서 NM의 버그를 수정했는데, 그동안 개발자들과 얘기를 나눴어요. 이에 따르면 ralink 공급업체 드라이버는 nl80211을 제대로 지원하지 않으며 WEXT 범위도 지원하지 않아 NM이 충돌하게 됩니다. 그들에 따르면, 그들은 드라이버 코드를 확인했고 드라이버가 도움을 받을 수 없으며 코드가 나빠 보인다고 말했습니다. 그는 또한 nm에게 드라이버를 무시하고 iw 또는 iwconfig를 사용하여 정적으로 구성하도록 지시할 수 있다고 덧붙였습니다.
최종 결과: 버그가 수정된 후 NM은 드라이버를 무시하여 드라이버를 로드할 때 즉시 충돌이 발생하지 않았습니다. 하지만 실행하면 wifi-menu동일한 충돌이 발생합니다.

sp는 의미 없는 값입니다.

따라서 어리석은 접근 방식은 NetworkManager를 objdump하고 해당 소스 코드를 읽어 [ip=00000000004ca126]이 segfault를 트리거하는 이유를 알아내는 것입니다.
