Hi all I am trying to port opensource kernel on top of Qualcomm board. I am struck at "local_irq_enable()" point in init/main.c, start_kernel() { --- snip --- call_function_init(); if (!irqs_disabled()) printk(KERN_CRIT "start_kernel(): bug: interrupts were " "enabled early\n"); early_boot_irqs_disabled = false; local_irq_enable(); } This functions implementation is like this... static inline void arch_local_irq_enable(void) { asm volatile( " cpsie i @ arch_local_irq_enable" : : : "memory", "cc"); } if i comment that local_irq_enable(), still the booting is not progressing. Can any one pls help me out here?? -- With regards, Sandeep Kumar Anantapalli,
