2.6.18-rc4 arch/x86_64/kernel/stacktrace.c::get_stack_end() incorrectly assumes that the irqstackptr is IRQSTACKSIZE aligned.
stack_end = (unsigned long)cpu_pda(cpu)->irqstackptr; if (stack_end) { stack_start = stack_end & ~(IRQSTACKSIZE-1);
irqstackptr is only guaranteed to be page aligned, not IRQSTACKSIZE (4*PAGE_SIZE) aligned.
