问题描述：
有3个节点做为glusterfs存储集群，通过ganesha对客户端暴露NFS共享卷。客户端通过NFS挂载卷并持续写入大文件。某日现大量Jan 18 05:17:28 node-1 kernel: NMI watchdog: BUG: soft lockup - CPU107 stuck for 22s! [migration/107:551]错误日志（见附件message日志）导致死机。远程SSH以及IPMI均无响应。查sa日志发现相同时间段内的cpu使用率某几个核心使用率为100%（与日志中所报的cou core能对应上。比如：CPU#107代表第107个核心）
附件中包含了sa日志及message日志

另外，这个问题我们在intel平台上没有出现过
