Isaku Yamahata 9bcfc7daab ioapic: when switches to level trigger mode, interrupts raised repeatedly. - the trigger mode is edge at first - During initializatoin, the interrupt is raised as edge which is masked. The corresponding bit of irr is set. - Then the mode is switched to level and it's unmasked. - the bit of irr is set, so the interrupt is raised repeatedly by ioapic_service(). - OS considers that the irq line is broken and falls back to polling mode. This patch fixes the issues. After raising edige, clear the bit of irr. > Bringing up interface eth0: > Determining IP information for eth0...irq 18: nobody cared (try booting with the "irqpoll" option) > Pid: 4126, comm: ip Not tainted 2.6.38-rc7 #1 > Call Trace: > <IRQ> [<ffffffff8105b009>] ? __report_bad_irq+0x38/0x87 > [<ffffffff8105b177>] ? note_interrupt+0x11f/0x188 > [<ffffffff8105bacf>] ? handle_fasteoi_irq+0xa7/0xd1 > [<ffffffff810046ff>] ? handle_irq+0x83/0x8c > [<ffffffff81003eb9>] ? do_IRQ+0x48/0xaf > [<ffffffff81300513>] ? ret_from_intr+0x0/0xe > [<ffffffff81031ab8>] ? __do_softirq+0x4f/0x114 > [<ffffffff81002d6c>] ? call_softirq+0x1c/0x28 > [<ffffffff81004647>] ? do_softirq+0x33/0x68 > [<ffffffff810316fb>] ? irq_exit+0x36/0x38 > [<ffffffff81015f2c>] ? smp_apic_timer_interrupt+0x88/0x96 > [<ffffffff81002853>] ? apic_timer_interrupt+0x13/0x20 > <EOI> [<ffffffff810177ed>] ? __ioapic_set_affinity+0x68/0x7c > [<ffffffff813000f0>] ? _raw_spin_unlock_irqrestore+0x8/0xa > [<ffffffff8105a84f>] ? __setup_irq+0x224/0x2cb > [<ffffffff8120e3c5>] ? e1000_intr+0x0/0x103 > [<ffffffff8105a9c7>] ? request_threaded_irq+0xd1/0x114 > [<ffffffff8120e396>] ? e1000_request_irq+0x34/0x63 > [<ffffffff8121237d>] ? e1000_open+0x81/0x11f > [<ffffffff8129097c>] ? call_netdevice_notifiers+0x45/0x4a > [<ffffffff81290d8d>] ? __dev_open+0x97/0xc4 > [<ffffffff8128e9c5>] ? __dev_change_flags+0xb9/0x13d > [<ffffffff81290cc1>] ? dev_change_flags+0x1c/0x51 > [<ffffffff812d0542>] ? devinet_ioctl+0x26e/0x594 > [<ffffffff812d174c>] ? inet_ioctl+0x92/0xaa > [<ffffffff81281d75>] ?
