我正在使用Adaptec ASA-71605H 主机总线适配器在 Ubuntu 12.04.4 上。
现代 Linux 内核附带了所需 pm80xx 内核模块的开源版本。Adaptec 自己提供了适用于 Ubuntu 12.04 的驱动程序，我测试了两者，效果相同。
我看到的症状是，有时启动后 16 个驱动器中只有 14 个可用。
完整dmesg日志可在此处获取有趣的是

第一个大块显示驱动器检测失败的样子，第二个大块显示驱动器检测成功的样子。
所有硬盘在投入完整组装之前都经过多次无错误测试。故障的硬盘并不总是相同的，似乎完全是随机的。
另一个问题表明错误来自共享的 IRQ 16，事实上，我有时会收到指向 IRQ 16 的错误日志。不幸的是，我不知道是否可以使用另一个 IRQ，因为 BIOS 不允许我这样做，并且从链路速度方面来看，使用另一个 PCIe 插槽不是一个选择。
任何帮助都欢迎。我即将订购一个 LSI 控制器，看看它是否有用，但希望它能与 Adaptec 配合使用。我只是非常担心将我的数据托付给这个控制器。
更新：问题还在继续。即使找到了所有驱动器，libsas 和 pm80xx 内核模块中也会随机出现内核崩溃。在生产中也无法使用。正在考虑购买 LSI 9201-16i……
