一臺centos5.5的服務器，前一天還使用正常，今天不停在終端中報log，具體信息如下：

無論是ssh上來的還是本機的終端窗口統統都報。都沒有辦法打字。
先停止syslog：
/etc/init.d/syslog stop
[root@localhost init.d]# lsmod | grep edac
i3200_edac 9545 0
edac_mc 26513 1 i3200_edac
[root@localhost init.d]# rmmod i3200_edac
[root@localhost init.d]# rmmod edac_mc
再開啓syslog：
/etc/init.d/syslog stop
用上面的步驟，卸載了兩個模塊，不報了。
回憶可能是在今天開機前將原來的光驅拔掉了，不只是否由於這個操作造成的。因爲除了這個沒有做過其他的改動（包括軟硬件）。
