There is a boot problem on x86_64 with efi that prevents
the linux-2.6 and linux-next trees from booting on SGI UV
hardware.

The code hits a BUG_ON() in arch/x86/mm/pageattr.c:184
------------------------------------------------------
static void cpa_flush_range(unsigned long start, int numpages, int cache)
{
unsigned int i, level;
unsigned long addr;

BUG_ON(irqs_disabled());
WARN_ON(PAGE_ALIGN(start) != start);

on_each_cpu(__cpa_flush_range, NULL, 1);
------------------------------------------------------

What is happening is in start_kernel() interrupts are
disabled. timekeeping_init() eventually calls
rotines that call change_page_attr_set_clr() which calls
cpa_flush_range() tripping BUG_ON(irqs_disabled()).

In init/main.c
------------------------------------------------------
asmlinkage void __init start_kernel(void)
[...]
preempt_disable();
if (!irqs_disabled()) {
printk(KERN_WARNING "start_kernel(): bug: interrupts were "
"enabled *very* early, fixing it\n");
local_irq_disable();
}
rcu_init();
/* init some links before init_ISA_irqs() */
early_irq_init();
init_IRQ();
prio_tree_init();
init_timers();
hrtimers_init();
softirq_init();
timekeeping_init(); <-- HERE
time_init();
profile_init();
if (!irqs_disabled())
printk(KERN_CRIT "start_kernel(): bug: interrupts were "
"enabled early\n");
early_boot_irqs_on();
local_irq_enable();
------------------------------------------------------

Possible solutions are to enable interrupts earlier,
call timekeeping_init() later, or change the code under
timekeeping_init() to not need interrupts enabled.

I have not gitbisected to find the source of the breakage.
My guess is it broke between 9/24 and 9/25.

I changed the BUG_ON() to WARN_ON() to get a backtrace
and added local_irq_enable(). Then the kernel booted.

Output with the WARN_ON():
