[Xen-devel] [PATCH][LINUX] all xen consoles must have CON_ENABLED set
I cannot think of any circumstance that the Xen console device would
not have CON_ENABLED. With out this, DomUs that panic() before the
init process has started (and maybe even after) do not get output hi
priority log_levels (like panic()) from LOG_BUF().
