我正在使用Ubuntu 12.04.4上的Adaptec ASA-71605H HBA构build一个ZFS NAS。
现代Linux内核附带所需pm80xx内核模块的开源版本。 Adaptec为Ubuntu 12.04提供了一个驱动程序，我testing了它们的效果。
我看到的症状是，开机后不时只能使用16个驱动器中的14个。
完整的dmesg日志可在这里 ，有趣的部分是

第一个大块显示一个驱动器检测失败的样子，第二个检测成功的样子。
所有的硬盘驱动器在进行完整的构build之前都经过了多次无误的testing。 这并不总是相同的驱动器退出，这似乎是完全随机的。
另一个问题表明，错误来自共享IRQ 16，事实上，我有时会有错误日志指向IRQ 16.不幸的是，我不知道是否有可能使用另一个IRQ，因为BIOS不允许这样的事情我和使用另一个PCIe插槽不是一个选项链接速度明智的。
任何帮助是非常受欢迎的。 我接近订购LSI控制器，看看它是否有帮助，但希望能与Adaptec合作。 我只关心我的数据到这个控制器。
更新 ：问题继续。 即使发现所有驱动器，libsas和pm80xx内核模块都会随机出现内核恐慌。 在生产中也不可用。 考虑获得LSI 9201-16i …
