[Xen-devel] Stability GPLPV - new test results

[Andreas Kinzler <ml-xen-devel@xxxxxx>]

Hello James,

something quite interesting happened during my stability tests. GPLPV 
0.11.0.213 which I consider stable, showed the same hang as the newer 
GPLPV versions. I now try to find out why even the stable 0.11.0.213 
hangs when it was and is stable on our production systems. There are 3 
possible causes: Xen 4.1.1 vs Xen 4.0.1, dom0 2.6.32.36 vs 2.6.32.18 and 
CPU Xeon E3-1230 vs Xeon X3450 [and board X9SCM-F vs. X8SIL-F].
The attached log show debugkeys for the hang. I find lines 64-66 quite 
interesting where is shows that there is an event channel upcall pending 
on the hung VM2, no problems on VM1 (line 52-54). Could that be a hint 
to the real problem?
Regards Andreas
