linux內核版本信息，制造linux內核異常,了解Linux內核中的異常

我想在非常低的溫度下調試我們的嵌入式Linux系統(< 40C)。問題是，它并不總是正確啟動，我試圖找出原因。經過一番分析，我看到內核啟動了下面的輸出期間進入恐慌：了解Linux內核中的異常

任何人可以給我一些提示如何解決這個問題？我想要的是了解系統的哪個組件(即內存芯片等)導致此故障。我會很樂意聽到任何想法。謝謝。

/opt/elinos-5.1/linux/linux-ppc-2.6.34/drivers/rtc/hctosys.c：無法打開rtc設備(rtc0)我認為問題是這樣的！ rtc(實時時鐘驅動程序)工作不正常，它可能是低溫影響其行為？ –
