[gentoo-user] [OT] Memory error messages in dmesg

[Dan Johansson]

I have started noticing the following messages in the dmesg output (and 
in the log-files) on my Gentoo rig:


[46545.779803] [Hardware Error]: Corrected error, no action required.
[46545.779984] [Hardware Error]: CPU:3 (15:2:0) 
MC2_STATUS[Over|CE|MiscV|-|AddrV|-|-|CECC]: 0xdc2540f40136

[46545.780434] [Hardware Error]: MC2 Error Address: 0x0002cc215138
[46545.780605] [Hardware Error]: MC2 Error: Fill ECC error on data 
fills.

[46545.783764] [Hardware Error]: cache level: L2, tx: DATA, mem-tx: DRD

[46545.791786] [Hardware Error]: Corrected error, no action required.
[46545.791958] [Hardware Error]: CPU:2 (15:2:0) 
MC2_STATUS[Over|CE|MiscV|-|AddrV|-|-|CECC]: 0xdc2540540136

[46545.792382] [Hardware Error]: MC2 Error Address: 0x0002cc2158b8
[46545.792579] [Hardware Error]: MC2 Error: Fill ECC error on data 
fills.

[46545.792791] [Hardware Error]: cache level: L2, tx: DATA, mem-tx: DRD
[46545.793088] mce: [Hardware Error]: Machine check events logged

I have been running memtest for some time (~100h) and have not gotten 
any error message - so I am suspecting that this is a CPU problem. Am I 
correct?


If it was just these error-messages I would not be that worried, but I 
have started to get a lot of "hangers" on this rig when compiling larger 
packages. Could there be a relation to the error-messages?

And an extended partition is a special type of primary partition.

Or you can avoid all this legacy idiocy and confusion by using GPT, which
lets you have a sensible number of partitions without fragile kludges.

Here are a couple links to bug reports from people who had a similar issue
with an AMD CPU.

Yes, DSS keys are now disabled by default, but can be re-enabled if
really needed. See http://www.openssh.com/legacy.html

The log I see says its not using the password but the key. I have regenerated 
the key but it didn't help. This setup has been fine for years. Could there be 
key *types* which became invalid, or now need special configuration, which was 
caused by the OpenSSL update?

Yes, it is an AMD CPU - I'll look into those links.

[gentoo-user] SDDM problem

[john]

Hello,

I have installed kde-frameworks-5.16 & kde-plasma-5.5 and when I start
sddm I get the following error:

/usr/bin/xauth: (stdin):1:  bad "remove" command line
/usr/bin/xauth: (stdin):2:  bad "add" command line

sddm does not start
Using openrc
Version x11-misc/sddm-0.13.0-r1

Any ideas? Does sddm only work with systemd??

slim is fine.

  OK, Primary and/or Extended partitions are numbered 1-to-4.  Logical
partitions within extended partitions are numbered 5 and up.

Not wanting to mess up my existing kde system I've built a new one from 
scratch in spare disk partitions, choosing the plasma profile and the kde 
overlay, and using openrc. My frameworks are at version 5.14.0 and kde-
plasma is at 5.4.3.

I did have a bit of trouble getting sddm to run at first, but after prowling 
around the Web for a while I got it to work without problem. Sorry I can't 
remember now what I did. It's at version 0.12.0-r1 here.

  The entire point of my bindmounting procedure (remember the original
post?) is to minimize the number of partitions without strangling root
if a logger goes wild.  I generally run with 3 partitions, including
swap.

Thanks for your hep and patience!
I want to report the full log.
I see the log file at /var/log/nx/nxserver.log is always 0 bytes. 
To try to enable it I changed the entry in /etc/nxserver/node.conf 
NX_LOG_LEVEL=0 to NX_LOG_LEVEL=6 but it still creates the 0 length log file.

I meant the log for the SSH server, on the machine you are trying to
connect to, not the nx log. On the SSH server, run

grep sshd /var/log/messages

If you use openrc then /etc/local.d/ would be a good place.

[gentoo-user] Autostart of an application for a headless embedded system

[Meino . Cramer]

Hi,

I have a Gentoo on my embedded system (Arietta G25, very tiny). 
If this system is booted (no display, no monitor, only one LED) 
an application (console only) should start, do its job and if done
shutdown the system. The application runs as root.
The system has no connection to the outside, so there are no
security related concerns...


What is the best place to call that application?


Thank you very much for any help in adnavce!
Best regards,
Meino

Hi wabe,

...thanks a lot! :
Yes I am using openrc...I asked because I was unsure not
to screw up the bootprocess...
