http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1698 ------- Comment #4 from at@xxxxxxxxxx 2010-12-20 10:33 ------- Passing dom0_mem=max:4GB to the hypervisor works around the issue.

I can't tell whether the command line switch is unknown or the problem yet exists. The output however, is very similar to the first dmesg and the kernel keeps crashing with the same message. The only difference is, that passing numa=off doesn't crash the the kernel immediately but after a bit where no output is shown on the console in the meantime (I guess Xen probes SRT tables on its own. Please note I have no idea what I'm talking about here, since I'm not familiar with such low level tasks, although I do know what NUMA is for). -- Configure bugmail: http://bugzilla.xensource.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. _______________________________________________ Xen-bugs mailing list Xen-bugs@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-bugs
