[win-pv-devel] bsod in xenbus.sys

[Walter Hofstädtler <walter@xxxxxxxxxxxxxxxx>]

Hi,

 

I reinstalled a Win 2012 R2 Server and got 3 times an IRQL_NOT_LESS_OR_EQUAL in xenbus.sys, Windows stopped with graphical screen, no reboot, simply stop. Unfortunately there was no memory.dmp file, nor any entries in event log.  I assume if xenbus.sys fails, Windows can’t write to disk any longer. All 3 BSOD are seen while installing software or updates.

 

Environment:

  Host: SLES 12 SP3, Intel server hardware,  

  DomU: Win 2012R2, XEN PV Driver 8.2.1.

 

Any ideas how to debug this issue?

 

 

Walter
