I'm seeing this boot crash reliably on x86-64 with the current tip. Is anyone else seeing this? suggestions for debugging, other than bisection? muli@undeg:~/vanilla$ hg tip changeset: 11433:1de184deaa9c tag: tip user: ssmith@xxxxxxxxxxxxxxxxxxxxxxxxxx date: Wed Sep 6 13:16:02 2006 +0100 summary: [XEN] gnttab: Initialise maptrack->flags (XEN) *** Serial input -> DOM0 (type 'CTRL-a' three times to switch input to Xen ).
