We uses HP Netraid Server with Integrated Netraid Controllers, the megaraid driver hangs with following error message:

megaraid: couldn't register IRQ 25

it breaks at the following position in the megaraid.c driver

/* Request our IRQ */

                if( adapter->flag & BOARD_MEMMAP ) {
                        if(request_irq(irq, megaraid_isr_memmapped, SA_SHIRQ,
                                                "megaraid", adapter)) {
                                printk(KERN_WARNING
                                        "megaraid: Couldn't register IRQ %d!\n",
                                        irq);
                                goto fail_attach;
                        }
                }
                else {
                        if(request_irq(irq, megaraid_isr_iomapped, SA_SHIRQ,
                                                "megaraid", adapter)) {
                                printk(KERN_WARNING
                                        "megaraid: Couldn't register IRQ %d!\n",
                                        irq);
                                goto fail_attach;
                        }
                }

when i turn off smp and disable the local apic option in the kernel the driver works fine.

Has anyone a solution for this problem ?? We need smp support on our servers.
