kernel: spurious 8259A interrupt: IRQ7

[blindfisch]

hallo,

ich habe folgende meldung in /var/log/messages stehen, danach ist der server abgesemmelt

Jan 17 18:20:10 server1 kernel: spurious 8259A interrupt: IRQ7.

was heisst diese melldung?

[captaincrunch]

Nach zwei Minuten googeln kam folgendes zum Vorschein :

A device with part number 8259A, which is a programmable interrrupt controller used with many devices to
interface with the system bus, has generated a unexpected Interrrupt. Asked for service without a real request.
ie. Noise.........

what lies around this line in the log file may give you a clue as to =
what device is actually generating the
interrrupt. If it only happens at boot time, it is possible that the =
device driver has a bug in it's
initialization routine that generates a spurious interrrupt to the OS. =
It should be reported appropriately.

If it happens all the time while the system is running, you have a bad =
hardware problem or something is
loose or improperly connected.
First ID the real source of the interrupt. The 8259A could be on many devices or it may be on the MB. (more than one present.)

(listman. redhat.com, aber auch massive Diskussionen auf der Kenrle-ML)

Wenn du mehr willst : http://www.google.de/search?q=%22spurio ... uche&meta=
Da wirst du dann zwar mal ein bisschen (selber) lesen müssen, aber das soll ja schließlich auch ein bisschen bilden ...

[blindfisch]

ok, ich hab mir mal einige links reingezogen, da steht fast überall das dies unbedenklich ist


jedenfalls ist das die letzte meldung gewesen bevor der server sich einfach aufgehangen hat. ping etc. geht noch, laut portscan ist port 22, 80 etc. auch offen - nur einloggen oder dienste nutzen geht nicht

[blindfisch]

könnte evtl. das etwas damit zutun haben?

Das sieht schon eher nach dem Problem aus. Ist das dein Rootie ? Sieht nämlich schon irgendwie nach Hardwareproblemchen aus.

[blindfisch]

ne, ist ne private kiste

den ram hab ich schon getauscht, trotzdem die gleichen fehler
