一次linux宕機日誌整理

分析messages日誌

一、interface ntpd[15867]: sendto(10.80.4.122): Invalid argument

linux修改了ip地址後沒有重起系統，ntpd服務作時間同步失敗，重啓linux系統

 

二、 interface kernel: ide-cd: cmd 0x3 timed out
      interface kernel: hda: irq timeout: status=0xd0
      interface kernel: hda: irq timeout: error=0x00
      interface kernel: hda: ATAPI reset complete

屏幕一直出現相似的報錯信息，懷疑是Linux核心中IDE模塊對DMA支持很差，解決方法以下：
修改Grub啓動菜單，加入ide=nodma參數，禁止IDE使用DMA接口。
kernel /boot/vmlinuz-2.6.18-53.smp ro root=LABEL=/ ide=nodma

 

三、interface syslogd 1.4.1: restart.
interface syslog: syslogd startup succeeded
interface kernel: klogd 1.4.1, log source = /proc/kmsg started.
interface kernel: Bootdata ok (command line is ro root=/dev/VolGroup00/LogVol00 rhgb quiet)
interface kernel: Linux version 2.6.9-67.ELsmp (brewbuilder@hs20-bc1-5.build.redhat.com) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-8)) #1 SMP Wed Nov 7 13:56:44 EST 2007

 

四、interface kernel: BIOS-provided physical RAM map:
