什么原因系统找不到第三片A1200P?

我使用环境:centos5.5 dahdi2.2.1.1 asterisk1.6.2.6
我使用一片卡是系统都能找到;使用三片卡时有时装新系统找不全,有时调下几个卡在pci插槽的次序,系统可以识别
有朋友说修改下卡的的中断,让他们共享一个中断即可是这样吗?
#lspci -v显示卡信息如下

#dahdi_genconf
#dahdi_cfg -vv后也没有发现第三块卡

Hi,
你可以调换一下PCI插槽，从BIOS里把USB禁掉，然后再重新加载一下驱动。

hi:
你朋友告诉你的是错误的。 如果换插槽不能工作的话，可能要修改pciid，重新编译。另外请检查驱动加载的报错信息，可能有问题方面的原因。

谢谢!
我以前也遇到过,换下pci插槽可以解决
