我遇到了Adaptec 5805 RAID卡的问题
http://www.adaptec.com/en-us/support/raid/sas_raid/sas-5805/
（RAID中有两张SAS光盘）和技嘉主板GA-H67A-D3H-B3

运行CENTOS 6作为networking服务器。
小故事：当我启动服务器时，RAID卡全速运行，传输速率超过250Mb / s。 在不超过60分钟的时间内，我收到一个IRQ错误，IRQ 16停止，从那时起，卡的传输速率不超过2.5Mb / s（但正在工作）。 我需要修复它，所以卡一直在全速运行。
很长的故事 ：
1]主板没有PCIe x8插槽来安装RAID卡。 我试过了x16插槽，但是在这个插槽里，根本没有检测到卡，系统没有这个插槽。 所以我用了x4插槽，这张卡（令人惊讶的是，对我来说）效果很好。 除了IRQ …
2]有两个SATA磁盘连接到主板上，每个主板都在主板上
三星HD502HJ三星HD103UJ
那么在正常的PCI插槽的第一个插槽中有附加的网卡（在上面链接的图片中，它是在主板上的“DUAL BOOT”描述旁边的最右边的白色PCI插槽。
RAID卡位于PCIeX4插槽（这三个白色PCI插槽旁边）
没有别的用途，我不使用任何USB设备或其他任何东西，只有两个SATA光盘，两个networking连接器（主板和卡）和RAID卡连接两个SAS光盘
3]系统就像我说的Centos 6

我没有看到任何IRQ 16冲突，build议irqpoll选项不会改变一件事情。 我不需要USB，所以我可以禁用它，但系统是生产的，所以我想知道，问题在哪里，在我开始混淆BIOS或任何其他事情之前（我也需要减less停机时间越多越好）。
任何人都可以帮我诊断问题吗？
