我有四个相同的节点，它们都建立在运行 OpenBSD 4.4 的 Supermicro 1025TC-TB 硬件上。其中两个节点是路由器，两个是负载平衡器。每组都以主动/被动配置运行，并由 CARP 提供故障转移功能。
活动路由器节点以每小时大约两个的频率记录这些错误：5 月 5 日 04:09:30 gw /bsd: ichiic0: 中止失败，状态 0x0
偶尔会弹出这个：5 月 5 日 03:59:41 gw /bsd: ichiic0: 中止失败，状态 0x40
我还没有发现这些记录的规律。ichiic 是 Intel SMBus 驱动程序。此主板还具有 I/OAT 功能，但 OpenBSD 不支持这些功能。我正在运行最新的 BIOS。
我怀疑这些是在中断峰值特别高时记录的，但 systat 速度太慢，我无法直接关联它。我也无法手动复制此问题。负载平衡器不受影响。
有任何想法吗？

答案1
您是否正在运行最新的 BIOS？这是我要检查的第一件事。
就我个人而言，我从未见过此错误（我运行的是 OBSD 4.4 开发箱）。我为您做了一些研究，我可以告诉您，不止一个人遇到过同样的问题（甚至在 ODBS 4.4 之前。我相信您也遇到过他们的帖子），但对此没有确切的答案。一些人将其归因于超线程，一些人将其归因于主板故障。
我会将其保留在我的待发现/学习事项列表中。抱歉我无法提供进一步的帮助。
答案2
该错误出现ichiic_i2c_exec()在ichiic.c并表示等待传输完成超时。如果这种情况很少见，那么我不会担心。但我会在日志（日志检查器？）中密切关注它。如果它开始更频繁地发生，我会怀疑硬件。
答案3
您可以尝试升级到快照，看看情况是否仍然存在吗？如果问题没有解决，可以向开发人员报告。
有一个令人讨厌的DoS 漏洞顺便说一下，在您使用的版本中。
