Re: [Xen-devel] Re: xen hg tree from yesterda hangs when kernel console is directed to ttyS0

No, sorry, implicit context here.  It really feels like a
serial line issue.  When I talk about using vga, it's
concurrent usage with com1.  I've never had a problem
with using only vga.  Although, that's a very small
percentage of my usage.

Even with *only* VGA?  I usually see exactly this with serial console
enabled: if I attempt it without sync_console, dom0 always hangs solid
very early in the boot process (though rarely at exactly the same
location.)  But I've never seen that sort of sporadic hang during boot
using just VGA console exclusively; the bugs I've seen have always been
either oopses or very predictable hangs at a specific location.
