Bug#522046: Still occurs
This bug continues to affect linux-image-2.6.26-2-xen-686 version
2.6.26-21lenny4 for me.
My dom0 is Ubuntu hardy running linux-image-2.6.24-27-xen version
2.6.24-27.67.
Here are two examples of the crash from within the domU - they both
occurred simply when running "aptitude install sun-java6-bin"
(sun-java5-bin is already installed sucessfully):
