I rent a server HP ProLiant DL120 G6 from Leaseweb.

root@lw4:~# uname -r
root@lw4:~# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

When checking the log with journalctl, I found two kernel errors:

root@lw4:~$ journalctl -p err
мар 23 17:29:40 lw4.domain kernel: ERST: Can not request iomem region <0x bf7ff000-0x bf800000> for ERST.
мар 23 17:29:40 lw4.domain kernel: i8042: No controller found

Tell me about what these errors? How to fix them?


A short and simple Google search for the above error shows you that it is a BIOS bug and it's harmless. You can disable it by adding quiet erst_disable to the default Grub cmdline.
