I had the same problem on a hardy amd64 hardy dom0 running xen 3.2 and kernel 2.6.24-21-xen. When I tried to install sun-java6-jdk on an i386 lucid domU.

I can confirm that the xen patch mentioned by Stefan in comment 58 solved my problem.

Before patching, the installation of sun-java6-bin crashed reliably, and calling 'dpkg --configure -a' showed this:

I applied the patch to the sources of xen-hypervisor-3.2_3.2.0_amd64.deb, rebooted with the patched hypervisor and the old dom0 kernel (2.6.24-21-xen).

The dpkg --configure step didn't crash the domU, and I can run tomcat6. Up to now, there has been no heavy load on the instance. I'll report back if I experience crashes.

Thank you, Stefan.
