...tput on boot: http://lists.xensource.com/archives/html/xen-users/2011-04/msg00340.html Unfortunately it got no replies. I was just wondering and hoping if any developers could answer the following questions: - Should I open a bug regarding the loss of serial console output on boot, and; - Is sync_console as bad an idea as the warning suggests it is? I get all my serial console output if I use sync_console, but I haven''t really put the machines under heavy load and would rather trade off truncated boot messages as opposed to performance under load.

When I reboot my system with xen with the following options to xen and vmlinuz, xen.gz com1=115200,8n1 console=com1,vga vmlinuz console=ttyS0,115200 console=tty0 the system hangs up while booting the dom0 kernel.

x86:x2apic: Disable x2apic on x86-32 permanently x2apic initialization on x86_32 uses vcpu pointer before it is initialized. As x2apic is unlikely to be used on x86_32, this patch disables x2apic permanently on x86_32. It also asserts the sanity of vcpu pointer before dereference to prevent further misuse.
