Hello,

On boot there is important log
(see https://pasteboard.co/HIfkzuA.png )
But I can't find it in /var/log/messages (or similar).

Is there a way to make it saved there too ?


Thank you,
ranran

/var/log/rc.log is what you want if /etc/rc.conf allows it:
/etc/rc.conf wrote:
# rc_logger launches a logging daemon to log the entire rc process to
# /var/log/rc.log
# NOTE: Linux systems require the devfs service to be started before
# logging can take place and as such cannot log the sysinit runlevel.
#rc_logger="NO"

# Through rc_log_path you can specify a custom log file.
# The default value is: /var/log/rc.log
#rc_log_path="/var/log/rc.log"

# If you want verbose output for OpenRC, set this to yes. If you want
# verbose output for service foo only, set it to yes in /etc/conf.d/foo.
#rc_verbose=no

# By default we filter the environment for our running scripts. To allow other
# variables through, add them here. Use a * to allow all variables through.
#rc_env_allow="VAR1 VAR2"

If you're talking about the hardware error on one CPU, that's before openrc starts, so it won't appear in rc.log. It should show in dmesg; if not, you need to do things in your kernel configuration concerning "Early printk" (I think it's under kernel hacking). If your are using syslog-ng there was a problem with early messages not being logged but that's fixed in recent releases unless you've tinkered with its default configuration, or you've got a very small buffer configured.

All that said, I suspect that sort of hardware error is bad news, and I doubt more logging will help.

<edit> I think you should run memtest - that looks like a memory error.

mce are log in /dev/mcelog
you need proper support in kernel to have the dev entry, and could use app-admin/mcelog to handle it.

I'm not sure if AMD cpus currently support mcelog. My Phenom-based desktop doesn't.
<edit>IIUC MCE's are now written to syslog, providing you have the right bits configured in the kernel; the mcelog device support appears to be deprecated.</edit>
