Summary: domain crash due to Kernel BUG at
"arch/xen/x86_64/mm/hypervisor.c":192
Product: Xen
Version: 3.0 (general)
Platform: x86-64
OS/Version: Linux-2.6
Status: NEW
Severity: normal
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: ludwig@xxxxxxxxxxx
We observe crashes of a SuSE Linux 10.0 system in a Xen-domain on a 2 Xeon
machine. The crash can be reproduced as follows:
1) Start Jobs so that all VCPUs are busy. E.g., I run
iteration=0 ; while /bin/true ; do \
iteration=$((iteration+1)) ; echo "iter $iteration" ; \
( sed 's/12345/23456/g' SomeFile > /dev/null ) ; done
simultaneously in five shells.
2) Start a Java-Prozess.
Then any user interaction commes to an immediate halt. On the console I see an
kernel error message like the following:

--------[end of kernel error message]--------------
The JVM was istalled from the JDK package from Sun's website:
cludwig@placidus:~> java -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
Xen - like the rest of the system - was installed from SuSE's packages.
I copied below the output of 'xm dmesg' and 'xm info placidus' run in the
domain0. (placidus is the crashing domain.) Please tell me if you need any
further information.
Regards
Christoph Ludwig
