一個內核報錯日誌分析與解決

問題

今天檢查jira服務器掛了的時候，查看了該服務器/var/log/messages日誌，發現報錯以下：

Dec  4 13:50:26 localhost kernel: pcieport 0000:00:1c.6: AER: Corrected error received: id=00e6
Dec  4 13:50:26 localhost kernel: pcieport 0000:00:1c.6: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e6(Receiver ID)
Dec  4 13:50:26 localhost kernel: pcieport 0000:00:1c.6:   device [8086:a116] error status/mask=00000001/00002000
Dec  4 13:50:26 localhost kernel: pcieport 0000:00:1c.6:    [ 0] Receiver Error        
Dec  4 13:50:26 localhost kernel: pcieport 0000:00:1c.6: AER: Corrected error received: id=00e6
Dec  4 13:50:26 localhost kernel: pcieport 0000:00:1c.6: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e6(Receiver ID)

Dec  4 13:50:26 localhost kernel: pcieport 0000:00:1c.6:    [ 0] Receiver Error

Dec  4 13:50:27 localhost kernel: pcieport 0000:00:1c.6: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e6(Receiver ID)
Dec  4 13:50:27 localhost kernel: pcieport 0000:00:1c.6:   device [8086:a116] error status/mask=00000001/00002000
Dec  4 13:50:27 localhost kernel: pcieport 0000:00:1c.6:    [ 0] Receiver Error

這種報錯多是因爲活動狀態電源管理正在將鏈路轉換爲較低的電源狀態，可能致使設備觸發這些錯誤。

 

解決

# 0.修改/etc/default/grub引導文件
[root@localhost ~]# cp /etc/default/grub /etc/default/grub.bak
[root@localhost ~]# vim /etc/default/grub

# 1.修改如下配置
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

# 2.保存關閉grub文件，更新grub引導，並重啓
[root@localhost ~]# update-grub
[root@localhost ~]# reboot
