I can confirm this. I managed to get a workaround by disabling VT (virtual technology) in BIOS. Message still exsist, so I don't think 'not booting' is releated to that message.
This happens to me only with Xen kernel. Some upstream toughts: http://lkml.org/lkml/2006/10/1/260 -- Does not boot on HP dc7600 USDT (regression from dapper) https://launchpad.net/bugs/58489 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
