So this error fires up for the first time in the context: i2c-piix4 version 2.7.0 (20021208) Advanced Linux Sound Architecture Driver Version 0.9.6 (Mon Jul 28 11:08:42 2003 UTC). request_module: failed /sbin/modprobe -- snd-card-0. error = -16 specify port specify port PCI: Setting latency timer of device 0000:00:1f.5 to 64 unexpected IRQ trap at vector a0 intel8x0: clocking to 48000 ALSA device list: #0: Intel ICH5 at 0xfebff800, irq 17 And later I'm getting also IPv6 over IPv4 tunneling driver irq 9: nobody cared!
