急，内核崩溃了！！BUG: soft lockup - CPU#0 stuck for 11s!

E文不太好，在kernel的maillist里也打到了相同的错误，是不是2.6.23-2.6.24的bug，怎样修复它呢！！

不知道你使用的时2.6.23的那个版本,应该是2.6.23.3中有关于soft lockup有相关描述SCHED_FIFO:99 and looping
for more than 10 seconds.

看了看,有说nfs-utils的问题,有说内核的问题,2.6.23.8~9有人测试过,暂时能解决此问题.
不过看了一下kernel上提交的nfs的patch，觉得nfsr的bug的可能性大。

谢谢wysilly
，只为了sky2支持性，没办法，只好升级2.6.24-rc6试试

看似发送死锁了, 被nmi的死锁检测查出来了

该问题解决了吗？
