这是在具有 8GB RAM 的 i2500 上运行 opensuse 11.4、内核 2.6.37.6-0.5-xen 的新服务器版本。
我尝试了几个不同的内核（恰巧通过 zypper 进行了更新），我分别尝试了两根 RAM（4GB）并交换了它们的位置。主板 DQ67OW 有集成显卡，我尝试了独立显卡，以防集成显卡占用了内核不知道的内存。任何 CPU 核心都可能出现错误。
它似乎没有被任何特定的活动触发 - 我正在运行 mdadm raid5，并且通常是“阻止”过程触发了 oops，但是 bash 和 udevd 也触发了它。
似乎如果某个足够关键的进程出现了问题，整个服务器就会挂起，大写锁定和滚动锁定灯会闪烁。
处理器、主板和 RAM 都是新的。我预计这是由硬件故障或驱动程序错误引起的。也许是网卡驱动程序……？
任何关于如何缩小罪魁祸首的建议都将非常有用。
干杯，
保罗

答案1
这通常是由于内存不足造成的，但正如您所说，也可能是由于软件错误造成的。（这相当于内核空间中的段错误。）
运行 memtest 一整夜。安装包后，它应该会显示为启动选项。
如果这没有发现任何问题，那么很可能是软件问题。比较不同的崩溃日志，看看第一行报告的地址或中途给出的调用跟踪是否有任何共同点。如果它们都非常相似，那么很可能是软件错误。将此报告为发行版的内核错误，看看您能得到什么帮助。
答案2
虽然我运行 memtest 的时间并不长，但我对 openSUSE 安装产生了怀疑。这是一个全新安装，但我的直觉是内核问题或类似问题。
因此我将 Debian 安装到不同的分区，并启动了我的虚拟机和其他一切，从此再没有出现任何故障。
我认为最有可能的原因是 Debian Xen 内核是 2.6.32，而 Opensuse 是 2.6.37。这可能是内核中的错误，或者只是配置不兼容。
等我有时间了，我会比较一下 .configs。它已经运行了几天，平均每小时都会收到一次错误，现在我不再收到错误了……
