Hi,

ich habe auf einer RedHat 5.4 ein Kernelupdate gemacht und während der Installation des NVIDIA-Treibers NVIDIA-Linux-x86_64-195.36.15 kam diese Meldung hier:

Kernel module compilation complete.

Ich vermute, dass das defekte Speicher sind. Der MEMTest hat allerdings nichts gebracht.
Und seit dem kommen beim User und beim Root in der Shell ständig die Fehlermeldungen:

[root@ceplx103 /]#
Message from syslogd@ at Thu Sep 30 15:45:13 2010 ...
ceplx103 last message repeated 34 times
[root@ceplx103 /]# [root@ceplx103 /]#
-bash: [root@ceplx103: command not found
[root@ceplx103 /]# Message from syslogd@ at Thu Sep 30 15:45:13 2010 ...
-bash: Message: command not found
[root@ceplx103 /]# ceplx103 last message repeated 34 times
-bash: ceplx103: command not found
[root@ceplx103 /]#
[root@ceplx103 /]

Meine Fragen sind

- ist das ein Anzeichen für defekte Speicherriegel?
- wie kann ich diese Fehlermeldungen von der Shell der User wegbekommen?

Vielen Dank und Grüße

Nelson

Vielen Dank

für Deinen Hinweis. Wie bist Du jetzt auf den Gedanken gekommen, dass das der RAM der Grafikkarte sein könnte?

Jetzt wäre es für mich interessant, ein Bencjmark-Tool zu haben, das die Karte extrem beansprucht, um zu sehen, dass exakt derselbe Fehler wieder auftritt.

Grüße
