这还分析什么，vxvm文件系统已经坏了，拆了再启动吧

doging

mount root分区失败，所以panic，检查硬盘吧

nimysun

应该是硬件问题，首先更换硬盘吧

adambbs

sun 第一次建议更换硬盘，更换硬盘后，发现问题依旧。 然后就更换了硬盘背板。系统就一切正常了。

byuq

明显的SCSI通道故障，首先考虑最容易更换的部件硬盘，然后考虑更换硬盘背板，最后考虑更换SCSI芯片所在的PCI I/O Board and System Controller。

alex_xie

硬盘坏了.

回复 1# adambbs


   这个panic就是一个简单的硬件问题，如果有panic的复杂问题请先配置好dumpdevice，然后收集coredump，否则贴出来的这点信息根本就不够分析。

一看就知道是高手，撒尿不按球，呵呵。
