系统每次restart，都会关闭硬盘，就像关机那样。然后重新启动硬盘。
对硬盘损坏很大，有的人还丢了分区表，大家还是先不要急着装

shaggy@austin.ibm.comJFS: [CHECKER] if txCommit fails, don't call d_instantiate
In several functions, d_instantiate is called before the transaction
is committed. Under the rare condition that txCommit fails, the new
inode is released, but the dentry continues to point to it. This
can lead to a seg fault. The fix is to call d_instantiate after
txCommit has run successfully.
