Xen - Dom0 Absturz mit 3.2
Hallo,
ich habe ein Problem mit den Backports von Xen.
Beim Starten einer der 8 Images (autostart) stürzt die Dom0 dann jeweils
ab, es ist nicht immer bei der ersten, spätestens aber bei der vierten
passiert der Fehler.
Es gibt diverse Meldungen über diesen Fehler (kernel BUG at
drivers/xen/core/evtchn.c:481!), leider immer für die 3.0er Versionen
und auch ohne echte Tipps woran man noch schrauben könnte.
Bei mir ist es auch exakt umgedreht, die Original Etch (3.0.3-0-4)
Version funktioniert einwandfrei und nur die Backports Version
(3.2.0-3~bpo4+2) stürzt jedes mal beim Booten ab.
Als Dom[0u] Kernel habe ich dabei jeweils 2.6.18-[56]-xen-686 probiert.
